Thermal Conductivity of Crystalline Polypyrrole

The purpose of this project is to investigate the thermal conductivity of crystalline polypyrrole (PPy) along its three-crystal directions. LAMMPS, a molecular dynamics simulator, was used to simulate PPy in a steady, crystalline state. PPy is parameterized and simulated from melting temperature to cooling temperature, thus allowing PPy to crystallize. Through analyzing the heat flux

How Surface Roughness Affects Interfacial Strength of Steel and Ice

In this project, researchers investigated how surface roughness affects the force needed to shear ice off of steel after it has been sprayed onto a cold surface. Steel specimens were prepared with various levels of surface roughness in which a bridging ice layer was formed from a spray. The force required to fracture the ice

Effect of Flow Rate on Interfacial Fracture between Ice and Steel

The researcher investigated how the flow rate of a misted water spray on cold surfaces affects the resulting ice structure and interfacial fracture strength. To accomplish this, a misting apparatus was constructed in which the distance between the misting nozzle and target surface is adjustable. The resulting ice layer was characterized and fracture tests were
