HEAT TRANSFER CALCULATIONS OF NON-DEVELOPED STEADY LAMINAR FLOW BETWEEN PARALLEL PLATES

Abstract

The objective of the current research is to investigate the developing laminar flow of a Newtonian incompressible fluid and heat transfer in the entrance region of a two parallel plate channel were investigated. The continuity, x-momentum, and energy equations were solved as a steady state in two dimension equations. The dimensionless technique was used. These equations have been represented by finite difference technique. This model has been solved by using the new method of implicit scheme, which would minimize the solution errors. The velocity profile becomes fully developed at approximately , and the temperature distribution becomes fully developed at approximately , as expected. The computational algorithm is able to calculate all the hydrodynamic properties such as velocities. Also the computational algorithm is able to predict all the thermal properties such as the temperature, bulk temperature, and local Nusselt number. The validity of thermal results for constant wall temperature and constant wall heat flux is verified and shows that there is a good agreement between the results of the present numerical solution and the correlation related to it.
