Enhancing heat transfer in miniaturized radiators is an important goal for many researchers. In this study, silver nanofluids were employed to improve the transfer of heat in micro-pin fin heat sinks. A thermal constant analyzer measured the thermal conductivity of the silver nanofluid samples using the transient plane source (TPS) technique. Results showed that the addition of silver nanoparticles to the working fluids improved thermal conductivity, but at high concentrations, ...
Synthetic polymers in starch-based polymer formulations improve the thermal and mechanical properties of the compounds. The purpose of this study was to develop and analyze foams containing ethylene-vinyl acetate (EVA) and varying concentrations of corn starch. A Thermal Constants Analyser measured the thermal conductivity of the EVA/starch samples using the transient plane source (TPS) method. Results showed that the thermal conductivity of the blends increased with starch content. The ...
Li-ion battery electrodes are typically mixed with carbon black materials which have low thermal conductivity in high-power-density battery applications. In this study, multi-walled carbon nanotubes (MWCNTs) were added to Li-ion battery electrodes to improve thermal conductivity. A measured the thermal conductivity of the electrode samples at room temperature using the transient plane source (TPS) method. Results showed that the addition of MWCNTs enhanced the thermal conductivity of the electrodes by ...
Intracavity transducers are probes used in early pregnancy scans. To ensure the transducers do not exceed the maximum temperature threshold when in close contact with embryonic and fetal tissues, a thermal test object (TTO) was designed to measure the temperature of the transducers when in contact with soft tissue. A tissue mimicking material (TMM) was fabricated in place of real human tissue and coupled with the transducer. A Thermal Constants ...
Lithium nitrate trihydrate (LiNO3·3H2O) has many traits that are desirable for thermal energy storage (TES) materials. This study tests the thermophysical properties of LiNO3·3H2O between 253-353 K in comparison to effective TES materials: water and paraffin. A TPS system measured the thermal conductivity of the solid LiNO3·3H2O samples using the transient plane source (TPS) method. Results showed that LiNO3·3H2O had a higher ...
