Modeling And Analyzing A Patch Of Human Red Blood Cell By Coarse-Grained Particle Method, Orhan Kaya Jan 2019

Modeling And Analyzing A Patch Of Human Red Blood Cell By Coarse-Grained Particle Method, Orhan Kaya

Theses and Dissertations

This thesis consists of three sections. First, some background information and theories about the erythrocyte membrane are provided. Second, a coarse-grained molecular dynamics model for a patch of erythrocyte membrane is built up. Third, the mechanical responses of the patch of red blood cells to diffusion and diffusivity, tension, rupture, and shear-induced pore area are analyzed.The patch of erythrocyte membrane is validated by modeling diffusivity and determining the diffusion coefficient constant. Then, the patch of the coarse-grained erythrocyte membrane is stretched uniformly until rupture. The critical stress/strain from simulation match with those obtained in experiments in laser optical ...


Efficient Modeling Of Latent Thermal Energy Storage Systems For Optimal Design And Operational Research, Chunjian Pan Jan 2019

Efficient Modeling Of Latent Thermal Energy Storage Systems For Optimal Design And Operational Research, Chunjian Pan

Theses and Dissertations

As a booming economy drives the need for more electricity, demands on freshwater for thermoelectric power generation also grow. Facing the limited freshwater resources, alternative dry cooling technologies such as air cooled condensers (ACCs) that reduce water consumption are becoming more prevalent. However, the performance of air ACCs is seriously deteriorated at ambient temperature. To address this challenge, a novel application of a Phase Change Material (PCM) based cooling system for supplementary cooling of ACCs is proposed. One of the engineering challenges that prevent the commercial application of latent thermal energy storage (LTES) systems is the lack of computationally efficient ...


Analysis Of Movement Of A 3t3 Cell With A Lamellipodium On A Substrate With Variable Rigidity, Alan Wopperer Jan 2019

Analysis Of Movement Of A 3t3 Cell With A Lamellipodium On A Substrate With Variable Rigidity, Alan Wopperer

Theses and Dissertations

Live cells move in the body in response to physiological and mechanical stimuli. Cells move using lamellipodium which extend beyond the leading edge of the cell. This lamellipodium is part of the cytoskeleton of the cell which pulls the cell forward in cell migration. It is observed that cells will move directionally depending on the stiffness of the substrate the cell comes into contact with. It is hypothesized that cells probe their environment to test the stiffness of their substrate. As a cell comes into contact with a substrate, the resulting force is dependent on how rigid or soft the ...

Computational Study Of Water Desalination Using Forward Osmosis, Ahmed Mohammed Alshwairekh Jan 2019

Computational Study Of Water Desalination Using Forward Osmosis, Ahmed Mohammed Alshwairekh

Theses and Dissertations

Forward Osmosis is a natural phenomenon that takes places across a semi-permeable membrane when there is a concentration difference across the membrane. Pure water permeates to the highly concentrated channel until the concentration across the membrane equilibrates. In water desalination applications, the same principle is applied. Spiral-wound membrane, flat sheet, or hollow fiber module are typical configurations in forward osmosis desalination modules. The application of water desalination using forward osmosis requires the existence of two channels separated by a suitable forward osmosis membrane. Sea or Brackish water is introduced in one side while the other side has a suitable draw ...


Performance And Stability Of Cacl2·6h2o-Based Phase Change Materials, Joshua Charles Jan 2019

Performance And Stability Of Cacl2·6h2o-Based Phase Change Materials, Joshua Charles

Theses and Dissertations

Thermal energy storage is receiving increased attention as the world transitions away from fossil fuels and seeks to improve the efficiency of existing energy production systems. While higher-temperature thermal energy storage has received the majority of attention in the field, thermal energy storage at temperatures close to ambient conditions may also have some practical applications. Hydrated salt phase change materials (PCMs) store thermal energy in this temperature range and can have high gravimetric and volumetric energy storage capacities while having a very low cost. Despite the benefits of these salts, they generally suffer from supercooling, phase segregation during cycling, and ...
