Journal of Engineering Physics and Thermophysics Aims and scope

In a low-frequency region an analytical expression has been obtained for the optimal frequency of gas-velocity fluctuations at which a maximum intensity of heat exchange between a gas and particles is attained. A comparison between the values of the frequency of gas velocity fluctuations obtained from the proposed expression with the results of numerical simulation for various diameters of particles is given.
