The influence of adding source terms to the liquid layer on the heat transfer for a laminar flow moving parallel to a horizontal heated flat plate has been simulated. A commercial multiphysics code, CFD-ACE+, was used and verified for Heat, Flow and VOF modules. Three subroutines were written for the mass and momentum source terms, which run as part of the code. Many parameters were changed by using these subroutines, for example, the mass flow rate, the nozzle spacing, the velocity magnitude, the layer thickness and velocity. It was found that the momentum of the spray has a major effect on the heat transfer. The simulations results showed promising results due to adding the source terms on improving the heat transfer.The spray was added to the liquid layer as a source term through the continuity and momentum equations. This source term was implemented into the code by the current investigator through the user subroutines which give flexibility inanbsp;...
