Abstract: The temperature field around a heasing solid sphere is measured with both laser holography and infrared scanning technique to study the hest transfer characteristics of solid particles in combustion. The local Nusselt number Nu along the sphere polar angle θ, the averaged Nusselt number Nit, as well as their empiral correlation affected by Re and Tb/T0 are obtained.

Key words: Forced convection, Heat transfer, Heating sphere
