| Summary: | 10, 100 and 1000. It was found that three dimensional 5, 0.6, 0. 7, 0.8. Heat transfer behavior was studied for A numerical investigation of laminar forced convective heat a three-dimensional laminar flow in a channel without above blockage ratios of 0.7. Higher heat transfer adiabatic. The trade-off between heat transfer enhancement analysis was performed using a finite volume approach. The and bottom walls, and the side walls were considered and pressure drop produced by the baffles was studied for baffles in which a uniform heat flux was applied to the top baffles. Parametric runs were made for Reynolds Numbers (Re) computer code was validated against the experimental results conductivity to fluid thermal conductivity ratios (K) of 1, effects were present for the range of Reynolds number enhancement due to an increase in the thermal conductivity enhancement was found for high Prandtl numbers (Pr--7. 0) of 150, 250, 3 50, and 450, for blockage ratios (H/Dy) of 0. of Goldstein and Kreid (1967) and Beavers et. al. (1970) for one obtained by increasing the blockage ratio. periodically fully developed flow (PDF). The numerical Prandtl Numbers (Pr) of 0. 7 and 7. 0, and for wall thermal ratio of the solid to the fluid regions is greater than the studied. The pressure drop penalty becomes highly important than for low Prandtl numbers (Pr--O. 7). The heat transfer transfer was performed in a three-dimensional channel with |
