Краткое описание

This work presents experimental and analytical studies of convection change phase heat transfer coefficient and pressure drop during flow inside tubes filled with porous media (sand). Condensation and evaporation processes were considered. Carbon dioxide was used as a flowing fluid over a wide range of inlet pressures, porosities, and mass flow rates. The pressure drop was found to be significantly reasonable in condensation and negligible for evaporation processes. The experimental results of the convective heat transfer coefficient and pressure drop during these flows were obtained, listed as experimental data, and used to develop empirical correlations using the dimensional analysis method. The analytical data produced from developed correlations were listed. Comparison between experimental results and those obtained analytically proved to be compatible with an average standard deviation (ASD) of 5.97% for pressure drop, while for the convective heat transfer coefficient during condensation process the ASD was 7.35%, and for the convective heat transfer coefficient during evaporation processes the ASD was 4.6%.
