Abstract Heat transfer and flow behavior of gas–solid suspension flows in a vertical plexi-glass tube of 28-mm inside diameter and of a uniform heat-flux boundary conditions was investigated. The measurement was performed using oil shale particles of a mean diameter of 972-µm. with different flow rates of air and solids loading ratio. The measured parameters were: inlet and outlet temperatures of the steam and air; exchanger wall and tube center temperatures at different axial locations; the differential pressure a cross an orifice manometer connected to the air blower; and pressure drop in the radial direction which was measured by L–type Pitot tube located at the end the test section. The results obtained showed that the average Nusselt number, defined in terms of the average local heat transfer coefficient, increases with increasing solids – loading ratio. Also a little deviation of the velocity profiles of solids and pure air were observed. The profiles tended to flatten in the center region as the loading ratio increased.
