Experimental investigations are made on the enhancement of forced convection heat transfer using thin inclined plates in a rectangular channel. The channel constructed with these plates has diverging and converging parts alternating along the flow passages. Heat transfer coefficient and pressure drop are measured for air flow at Reynolds numbers ranging from 1.2×10^4 to 4.8×10^4. Performance comparison is made under the condition of constant pumping power. Large enhancement in the heat transfer coefficient is achieved as the angle of inclination increases, with accompanying large pressure drops. The channels with clearance at the peaks of converging-diverging parts are tested in order to decrease the large pressure drops. When the clearance is perpendicular to the mainstream direction, an improvement in performance is observed.
