NUMERICAL PREDICTION OF FLOW FIELD AND HEAT TRANSFER FROM A ROW OF LAMINAR SLOT JETS IMPINGING ON A FLAT PLATE
Résumé
The present work deals with the numerical
prediction of flow field and heat transfer of
laminar jets issuing from a row of two-dimensional
slots. The jet impinges normally on an isothermal
flat plate. Moreover, the effect of the velocity
profile at the nozzle exit on both heat and momentum
transfer has been investigated.
The numerical model is based on solving the finite difference forms of the conservation equations. The solution procedure is itterative due to the elliptic nature of the flow.
Numerical computations are carried out for different Reynolds numbers and various nozzle spacings. The present numerical results for local Nusselt number for the limiting case of a single jet showed excellent agreement with the available experimental data.
