This paper describes an experimental study on impinging jet heat transfer of gaseous solid suspension Flow. Impinging jet is a typical examine of nonstraight Flow wherein heat transfer performance can be improved to a great extant due to the inertia difference between both phases. In the present study, the surface upon which the jet impinges is concaved so that the heat transfer enhancement due to the presence of the suspended solid particles in not confined within somewhat narrower impinging region but in extended to the wall jet region. Experimental results reveal that the observed increase in the convective heat transfer coefficient due to the presence of the solid phase exceeds the usual contribution of the increased heat capacity of the Flowing media and the merit of using the concaved for the heat transfer enhancement is apparent.
