| Abstract: |
An optimal rib geometry was investigated experimentally and numerically in the present work to give an enhancement ofheat transfer coefficient and fluid flow characteristics at equal mass flow rate and pumping power constraints through the cooling passage. Two different rib shapes (grooved square and inverted trapezoidal) were conducted to investigate its effects on the fluid flow and heat transfer characteristics. The experimental correlations of the average Nusselt number ratio (NulNu.) with different rib shapes are developed in terms ofReynolds number and rib pitch in eq. (1). Nu/ Nus = a.Re-o.lo264 .(p/e)-D·208 (1) (2.3 x 10^4 |
