Abstract

This study presents the results of transient mixed convective flow over discrete uniform heat flux components simulating electronic modules mounted on vertical parallel boards. Each board includes adiabatic and heated flush segments with finite thermal capacity. The computational scheme used in the solution is entitled 'Simple Arbitrary Lagrangian Eulerian' (SALE) that is modified to include the energy balanced boundaries of the heated segments with consideration of the surface heat capacity. The full two-dimensional equations governing the flow and energy fields are solved. In the experimental part, temperatures at different surface locations and velocity distributions are evaluated and are compared with the predicted results by SALE. Fairly good agreement is established between the experimental and predicted results for the component temperature profiles. No overshoot in temperature was observed in both experimental and numerical results. The investigation is extended to relate the Nusselt number for each source to the flow Reynolds number.
