Frequency Dependent Multiphase Flows On Centrifugal Microfluidics., Esmail Pishbin, Amin Kazemzadeh, Mohammadreza Chimerad, Sasan Asiaei, Mahdi Navidbakhsh, Aman Russom

EGS Content

The simultaneous flow of gas and liquids in large scale conduits is an established approach to enhance the performance of different working systems under critical conditions. On the microscale, the use of gas–liquid flows is challenging due to the dominance of surface tension forces. Here, we present a technique to generate common gas–liquid flows on a centrifugal microfluidic platform. It consists of a spiral microchannel and specific micro features that allow for temporal and local control of stratified and slug flow regimes. We investigate several critical parameters that induce different gas–liquid flows and cause the transition between stratified and slug …

Environmental And Economic Implications Of Energy Efficiency In New Residential Buildings: A Multi-Criteria Selection Approach, Florida Solar Energy Center, Delia D'Agostino

FSEC Energy Research Center®

The choice of the most appropriate technologies in buildings is often a challenge at the design stage, especially when many different criteria are taken into account. Consequently, the decision process relies often on one criterion only, such as costs or energy savings. We propose a multi-criteria approach based on multi-attribute utility theory to assess alternative energy efficiency measures, explicitly considering both environmental and economic criteria. We apply it to the design of a new residential building in Milan (Italy), with the aim to maximize CO₂ emission savings related to electricity and gas consumption, and to minimize embodied energy and …

How Will Climate Alter Efficiency Objectives? Simulated Impact Of Using Recent Versus Historic European Weather Data For The Cost-Optimal Design Of Nearly Zero Energy Buildings (Nzebs), Florida Solar Energy Center, Delia D'Agostino

FSEC Energy Research Center®

Achieving "nearly zero energy buildings" (NZEB) has been established as a vital objective over the next decade within the European Union (EU) [1, 2]. Previous work has shown that a series of very cost-effective thermal efficiency measures, equipment, appliance and renewable energy choices are available across climates to reach the NZEB objective. Resulting detailed energy and economic optimization findings have been obtained and published. One area that has just begun to be explored, however, is how selection of weather files and their application against coming climate change can influence outcomes from energy optimization procedures.

Maximizing The Effectiveness Of Ductless Heat Pumps In Existing Homes By Demonstrating Integrated Controls: Measurement And Verification Plan, Florida Solar Energy Center, Eric Martin

FSEC Energy Research Center®

There is a trend for homeowners to install efficient ductless air-source heat pumps (ASHP) as a supplement to less efficient existing space conditioning systems, with most homeowners adding one unit in a central living area. Because of the potential for ASHPs to save energy by providing a large portion of the space conditioning, utilities have incentivized this strategy. However, post installation evaluations suggest ASHPs are not reaching their full potential because the existing heating system continues to operate more than necessary. This report describes a measurement and verifications strategy for a research project that aims to maximize savings from supplemental …

Evaluating Moisture Control Of Variable-Capacity Heat Pumps In Mechanically Ventilated, Low-Load Homes In Climate Zone 2a, Florida Solar Energy Center, Eric Martin

FSEC Energy Research Center®

The well-sealed, highly insulated building enclosures constructed by today's home building industry coupled with efficient lighting and appliances are achieving significantly reduced heating and cooling loads. These low-load homes can present a challenge when selecting appropriate space-conditioning equipment. Conventional, fixed-capacity heating and cooling equipment is often oversized for small homes, causing increased first costs and operating costs. Even if fixed-capacity equipment can be properly specified for peak loads, it remains oversized for use during much of the year. During these part-load cooling hours, oversized equipment meets the target dry-bulb temperatures very quickly, often without sufficient opportunity for moisture control. The …

Tailoring Materials Behavior Using Geometry, Hessein Ali, Hossein Ebrahimi, Ranajay Ghosh

EGS Content

Many applications require materials whose response can be tuned such as morphing wings for supermaneuverable vehicles, soft robotics and space structures. Nature achieves this objective using external dermal features – skin, furs, tooth, feathers. These nonlinearities are generated using the geometry and topology of the scales The scales provide distinct structural advantages such as protection and tailorable response from scales contact Scales also aid in highly dynamic life functions – such as locomotion, anti-fouling, flapping flights, swimming. Material to structural correlations are highly nonlinear due to scale topology. We aim to reveal structure-property-architecture correlations for automated 3D printed designs.
