Effects of Heating Temperature on the Isothermal Performance of a Potassium Concentric Annular Heat Pipe

Energies, 2022
For high-precision thermocouple calibration, the uniformity of the temperature field provided by the metal temperature equalizing block is low, and the structure of the gas-controlled heat pipe is complex. In order to improve the thermocouple calibration

HEAT TRANSFER ENHANCEMENT IN LAMINAR CONVECTIVE HEAT TRANSFER WITH NANOFLUIDS

Proceeding of TMNN-2011. Proceedings of the International Symposium on Thermal and Materials Nanoscience and Nanotechnology - 29 May - 3 June , 2011, Antalya, Turkey, 2011
In order to utilize nanofluids in practical applications, accurate prediction of forced convection heat transfer of nanofluids is necessary. In the first part of the present study, we consider the application of some classical correlations of forced convection heat transfer developed for the flow of pure fluids to the case of nanofluids by the use of ...
