Heat transfer phenomenon of fluids in corrugated plate heat exchangers

Abstract

Heat transfer is great attention in every Industrial application. While designing the heat exchanger two important factors are must be considered one is the least amount of pumping power (minimum Pressure drop) and most efficient heat transfer for given conditions. The configuration of heat Exchangers is extent effects on the above two factors. The corrugated heat exchanger comes under special type of heat exchangers.This type heat exchanger recover more heat than the other type of heat Exchangers because of they are arranged to form a package due to this is compact form of heat having less weight, and less space and providing high heat transfer coefficients than the other types. The heat transfer coefficient and friction factor of water, water+sio2 are determined for flow under corrugated heat exchanger at corrugation angles of 30°,40°,50°.Experiments are under taken laminar flow region at bulk temperature of 60° c. The experimental results shows that enhance in Reynolds number causes increase in heat transfer coefficient and 50°corrugated angle gives optimum result due to high turbulence created at low velocities.
