The behavior of fine glass particles and their influence on fluid motion are investigated in a flow over a flat plate downstream of a two-dimensional slit injection. Heat transfer characteristics are examined in terms of the mass loading ratio of the particles ranging up to 0.8 and particle size varying from 68.6 to 148 μm in mean diameter. The particles promote turbulence of the fluid in a weakly turbulent flow, but suppress turbulence in a strongly turbulent flow. The heat transfer characteristics along the wall are well correlated to the variation of turbulent flow field due to the effect of the particles.
