Data Approximation Strategies Between Generalized Line Scales And The Influence Of Labels And Spacing, Jonathan C. Kershaw, Cordelia Running

Department of Food Science Faculty Publications

Comparing sensory data gathered using different line scales is challenging. We tested whether adding internal labels to a generalized visual analog scale (gVAS) would improve comparability to a typical generalized labeled magnitude scale (gLMS). Untrained participants evaluated cheeses using one of four randomly assigned scales. Normalization to a cross‐modal standard and/or two gLMS transformations were applied to the data. Response means and distributions were lower for the gLMS than the gVAS, but no difference in resolving power was detected. The presence of labels, with or without line markings, caused categorical‐like lumping of responses. Closer low‐end label spacing for gLMS increased …

Cripping Modernism: An Introduction, Maren Linett

Department of English Faculty Publications

This introduction briefly introduces literary disability studies and crip methodology. After informing readers about a few key concepts of disability studies and giving some examples of modernist writers’ use of disability metaphors, it raises questions about how disability inflects modernist themes and modernist form. It then offers synopses of the nine articles in the special issue, articles that treat a range of authors from the early to mid-twentieth century. The essays engage with literary theory, various early twentieth-century historical contexts, and issues of race, imperialism, gender, sexuality, and class.

Experimental Investigation Of Boiling Regimes In A Capillary-Fed Two-Layer Evaporator Wick, S. Sudhakar, J A. Weibel, S V. Garimella

CTRC Research Publications

Vapor chambers with transformative evaporator wick designs capable of passively dissipating high heat fluxes over large areas, while maintaining low thermal resistances, can meet the thermal management needs of next-generation power semiconductor devices. Our prior work proposed a two-layer evaporator wick structure to enhance the performance of vapor chambers operating at high heat fluxes. The current study experimentally characterizes the capillary-fed boiling heat transfer behavior in such a two-layer evaporator wick, compared to a homogeneous (single-layer) wick, over a 1 cm2 evaporator area. The two-layer design comprises a thin base wick layer that is fed with liquid from a thick …

Simultaneous Wick And Fluid Selection For The Design Of Minimized-Thermal-Resistance Vapor Chambers Under Different Operating Conditions, K. Baraya, J. A. Weibel, S V. Garimella

CTRC Research Publications

The thermal resistance of a vapor chamber is primarily governed by conduction across the evaporator wick and the saturation temperature gradient in the vapor core. The relative contributions of these two predominant resistances can vary dramatically with vapor chamber operating conditions and geometry. In the limit of very thin form factors, the contribution from the vapor core thermal resistance dominates the overall thermal resistance of the vapor chamber; recent work has focused on working fluid selection to minimize overall thermal resistance in this limit. However, the wick thermal resistance becomes increasingly significant as its thickness increases to support higher heat …

A Permeable-Membrane Microchannel Heat Sink Made By Additive Manufacturing, I. L. Collins, J. A. Weibel, L. Pan, S V. Garimella

CTRC Research Publications

Microchannel heat sinks are capable of removing dense heat loads from high-power electronic devices with low thermal resistance, but suffer from high pressure drops due to the small channel dimensions. Features that reduce the pressure drop, such as manifolds, increase fabrication complexity and are constrained by traditional subtractive manufacturing approaches. Additive manufacturing technologies offer improved design freedom and reduced geometric restrictions, expanding the types of features that can be produced and integrated into a heat sink. In this work, a novel permeable membrane microchannel (PMM) heat sink geometry is proposed and fabricated using direct metal laser sintering (DMLS) of an …

A Coupled Wicking And Evaporation Model For Prediction Of Pool Boiling Critical Heat Flux On Structured Surfaces, H. Hu, J. A. Weibel, S V. Garimella

CTRC Research Publications

Boiling is an effective heat transfer mechanism that is central to a variety of industrial processes including electronic systems, power plants, and nuclear reactors. Micro-/nano-structured surfaces have been demonstrated to significantly enhance the critical heat flux (CHF) during pool boiling, but there is no consensus on how to predict the structure-induced CHF enhancement. In this study, we develop an analytical model that takes into consideration key mechanisms that govern CHF during pool boiling on structured surfaces, namely, capillary wicking and evaporation of the liquid layer underneath the bubble. The model extends existing wicking-based CHF theories by introducing the competing evaporation …

Design Of An Area-Scalable Two-Layer Evaporator Wick For High-Heat-Flux Vapor Chambers, S. Sudhakar, J. A. Weibel, S V. Garimella

CTRC Research Publications

A hybrid two-layer evaporator wick is proposed for passive, high-heat-flux dissipation over large areas using a vapor chamber heat spreader. For such applications, the evaporator wick layer must be designed to simultaneously minimize the device temperature rise and minimize the flow resistance to capillary feeding of the wick. This requires a strategy that exploits the benefits of a thin wick for reduced thermal resistance and a thick wick for liquid feeding. In the present design, a thick cap layer of wick material evenly routes liquid to a thin, low-thermal-resistance base layer through an array of vertical liquid-feeding posts. This two-layer …

The Petal Effect Of Parahydrophobic Surfaces Offers Low Receding Contact Angles That Promote Effective Boiling, T. P. Allred, J. A. Weibel, S V. Garimella

CTRC Research Publications

Despite extensive study of boiling processes and their widespread use in industry, critical interactions between the fluid and surface during boiling remain poorly understood. Simplistic, static descriptions of the contact angle are still relied upon to describe the effects of surface wettability on dynamic interfacial processes that govern boiling. This work demonstrates the critical role of the dynamic wettability characteristics of a surface on bubble growth dynamics and boiling performance. In spite of their superior nucleation behavior, hydrophobic surfaces have received little attention for boiling applications due to their typically premature transition from efficient nucleate boiling to inefficient film boiling. …

Integrating Technical Standards Into Et Curricula To Meet Abet Standards And Industry Needs, Paul B Mcpherson, Margaret Phillips, Kyle Reiter

Libraries Faculty and Staff Scholarship and Research

With technical standards affecting nearly every aspect of our daily lives, from computers to the components and materials used in car engines, it is critical that undergraduate students are educated on the importance of standards and provided with opportunities to locate and apply relevant technical standards to real world situations. In addition, with ABET accreditation requiring students to have a “basic understanding and familiarity with,” and experience “using” codes and standards, faculty need to consider how such material can be naturally integrated into the curriculum.

At Purdue University, education about codes and standards has been integrated into the mechanical engineering …

Standards Collections: Considerations For The Future, Margaret Phillips

Libraries Faculty and Staff Scholarship and Research

Technical standards are a form of gray literature that describe consensus for a wide variety of applications. They promote safety, quality, and interchangeability of parts. In academic libraries, standards have largely been associated with engineering collections, despite having connections to many disciplines. Engineering and technology accreditation bodies and employers continue to expect graduates to have knowledge and experience with standards upon graduation. This article provides a brief history of standards collection development in academic libraries, discusses the challenges of standards collections, shares a case study of standards information literacy curricula integration, and offers considerations for the future of standards collections.

Contaminant Release From Storm Water Culvert Rehabilitation Technologies: Understanding Implications To The Environment And Long-Term Material Integrity, Andrew J. Whelton, Kyungyeon Ra, Seyedeh Mahboobeh Teimouri Sendesi, Md Nuruddin, Xianzhen Li, John A. Howarter, Jeffrey P. Youngblood, Chad T. Jafvert, Nadezhda N. Zyaykina

JTRP Affiliated Reports

Millions of miles of existing U.S. storm water culverts are critical for roadway safety but much of this infrastructure requires repair. State departments of transportation (DOT) are increasingly choosing to rehabilitate culverts with spray-on and cured-in-place pipe (CIPP) lining processes. These culvert lining practices involve the manufacture of a new plastic liner inside a damaged culvert. DOTs are selecting these outdoor plastic manufacturing methods partly to avoid open-trench excavation, which can cause traffic disruption and work zone traffic safety issues. This study was conducted to better understand current knowledge about culvert lining caused environmental contamination, final product quality, and recommend …
