TURBULENT FORCED-CONVECTION WITH SINUSOIDAL VARIATION OF INLET TEMPERATURE BETWEEN 2 PARALLEL-PLATES

The thermal entry region heat transfer due to turbulent forced convect ion, subjected to a sinusoidally varying inlet temperature is solved b y employing a hybrid numerical-analytical solution technique under lin ear variation df wall temperature and constant wall temperature as bou ndary condition and is verified with the experimental results. The ana lytical solution of the problem is obtained through extending the gene ralized integral transform technique. An experimental set-up was built and used in order to validate the employed mathematical modeling. Ana lytical solutions are compared with the experimental findings. Satisfa ctory agreement is obtained between theoretically and experimentally d etermined heat transfer characteristics for different axial positions along the channel. Heat transfer characteristics of flow have been det ermined for linear wall temperature and constant wall temperature boun dary conditions. Results obtained from the analytical-numerical soluti on technique and experimental studies have been presented in graphical and tabular forms. Copyright (C) 1996 Elsevier Science Ltd
