The effects of combined convection and radiation heat transfer for laminar flow between parallel plates are investigated, and an experimental study of the convection theory is made. The von Mises transformation is applied to the equations of motion and the convection energy equation the equations are then written in finite difference form for numerical solution. For the combined heat transfer problem one plate is insulated and the other is maintained at a uniform temperature. The governing radiation equations are developed assuming black plates with the entrance and exit of the channel participating in the radiative energy exchange. The plates were in one of three configurations both plates at uniform temperature, top plate heated and bottom plate insulated, or bottom plate heated with the top plate insulated. An interferometer was used in the investigation and the measured temperature profiles and Nusselt numbers are compared with theoretical values obtained from the numerical solution of the governing equations.
