Numerical Study for Fluid Flow and Heat Transfer Characteristics in a Corrugating Channel

To support and improve the results of the intensive studies that performed on developing the thermal systems and enhancing their thermal performance, experiments were conducted on 2D-Corrugated channels (L=450 mm) with a number of geometric shapes of corrugation (sinusoidal, triangular and square) with fixed hight of amplitude of corrugation (8 mm) In addition, four corrugation angles (25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees) the triangular corrugated channel. The study applies Reynold numbers range between 500 and 2500. The tests have been done theoretically by using FLUENT a comparison has been done among the results of heat transfer and friction factor of the corrugated channels and the smooth channel, A high enhancement in the overall performance was found specially in the triangular corrugated channel with raise in the value of pressure drop. In addition, the obtained results of Nusselt number and friction factor of five angles present that the greatest angle gives the highest values of Nusselt number and friction factor Acceptable agreement was gained when a compassion was conducted among the current results and previous studied.
