PRESSURE DROP STUDIES IN WAVY CORRUGATED PLATE HEAT EXCHANGERS

Wavy type heat exchangers are one of the prominent corrugated plate heat exchangers. The experimental studies have been carried out on wavy type heat exchangers with glycerol and water as test fluids. The experimental work involves in studying the various factors affecting the fluid flow mostly Friction factor and Pressure Drop , where the energy losses are calculated across the wavy type corrugated plate heat exchanger. The pressure drop studies were carried out in a corrugated plate heat exchanger with different corrugation angles of 30˚, 40˚ and 50˚ and corrugation channel spacing of 15 mm. It has been found that the pressure drop increases with an increase in the corrugation angle and viscosity of test fluid. Experimental data has been plotted for pressure drop against Reynolds number and observed that the pressure drop increases with increase in the corrugated angle.
