Summary
In a fluidized bed of high gas velocities, particle impact on an immersed surface is an important mechanism for heat transfer. The heat exchange between an impacting spherical particle and surface is analyzed by considering (1) the heat conduction through the time varying contact area during the period when the particle is in contact with the surface, and (2) the heat conduction through the surrounding gas during the period when the particle is approaching and rebounding from the surface. For the solid conduction problem, an analytical solution is obtained for small Fourier numbers, and a correction factor is computed numerically to be used for large Fourier numbers. For the gas conduction problem, a solution is obtained by combining three analytical solutions each valid in a certain region of the gas domain. Since heat transfer due to the impact of a stream of falling particles was also measured with a simple experimental set up. 53 refs., 15 figs., 1 tab.
