HEAT TRANSFER IN PACKED BEDS AT BOTH PORE SCALE AND MACROSCOPIC LEVEL
摘要
Some questions relative to heat transfer in two-phase systems are reviewed with the help of new experiments for nylon-water and brass-water systems. The chosen particle diameter allows a direct measurement of pore-scale temperatures. The experimental data are analysed in terms of a two-temperature model with a volumic heat transfer coefficient. In a second approach of this problem our experimental results are compared satisfactorily with some predictions obtained from volume averaging theories.
