Numerical simulation of heat transfer at an array of co-planar slat-like surfaces oriented normal to a forced convection flow

Numerical study of the per-slat heat transfer coefficient was made for an a rray of co-planar slat-like surfaces which face upstream into an oncoming a irflow. The flow washes over the slats as it passes into slot-like gaps bet ween the slats. The computations were performed for several different slat- slot configurations characterized by the ratio of the slot-slat width to th e slat width (P/W), the Reynolds number varied from 500 to 7000, and the ra nge of Prandtl number was 0.7-10. Based on the SIMPLER algorithm and the ce ntral difference scheme (CDS), parametric studies on the effects of the Rey nolds number, P/ Wand the Prandtl number were performed. Numerical results agree well with the test results for mass transfer(Se = 2.5). From the nume rical results, a general heat transfer correlation was obtained which cover s the following range of parameters: 500 less than or equal to Re less than or equal to 7000. 1.25 less than or equal to P/W less than or equal to 5, 0.7 less than or equal to Pr less than or equal to 10.
