In this study, multi-walled carbon nanotubes (MWCNTs) were added to Al2O3/water nanofluids to determine their heat transfer and temperature drop properties compared to water and Al2O3/water nanofluids. A TPS thermal constants analyzer measured the thermal conductivity of the Al2O3/water nanofluids using the transient plane source (TPS) method. The thermal conductivity of Al2O3/water nanofluids was further enhanced with the addition of MWCNTs because ...
Many conventional fluids have low thermal conductivities. Adding thermally conductive nanometer-sized particles to these fluids transforms them into thermally conductive nanofluids. In this study, the thermal conductivity of aqueous alumina and multi-walled carbon nanotube (MWCNT) nanofluids was measured using the transient plane source (TPS) method with a thermal constants analyzer TPS. During each trial, 0.015 W of power were administered to each sample for two seconds. Results of the experiment showed ...
Many conventional fluids have low thermal conductivities. Adding thermally conductive nanometer-sized particles to these fluids transforms them into thermally conductive nanofluids that can be used for refrigeration and air conditioning systems. In this paper, the transient plane source (TPS) method is used to explore the thermal conductivity of multi-walled carbon nanotube (MWCNT) nanofluids in a helically coiled, double-pipe heat exchanger. The thermal conductivities of the MWCNT nanofluids were measured using ...
Numerical models for the calculation of thermal conductivity and rheology behavior of alumina and multi-walled carbon nanotube (MWCNT) nanofluids were evaluated by determining these properties experimentally and comparing the results to the models. The thermal conductivity was measured by the transient plane source method, and the dynamic viscosity was determined using a rotational rheometer. A new model was then developed for these nanofluids, including the effects of interfacial thermal resistance. ...
