Fluid flow and heat transfer characteristics are analyzed for the laminar forced-convection flows in a parallel-plate channel with an array of fins mounted on the wall. The two plates are maintained at uniform but unequal temperatures and the mounted fins are assumed to be perfectly conductive. Numerical solutions for the Reynolds number within the range 10 ≤ Re ≤ 300, fin height within 0 ≤ e H ≤ 0·5, and fin pitch within 0 ≤ d H ≤ 4 are presented. Analytical solutions for the infinite and zero pitch cases, representing the lower-bound and upper-bound values, respectively, are developed and compared with the numerical predictions. Results show that both the heat transfer and friction factor (i) increase with the Reynolds number and (ii) are highly sensitive to the geometric arrangements.
