Numerical investigation of conjugate natural convection in closed region under radiation heating of one boundary
The paper introduces the results of numerical solution of heat transfer problem in closed rectangular region in free convection using the conjugate heat transfer model. Gas infrared emitters arranged horizontally in upper part of simulation region have been considered as the heating source. Plane no...

| description | The paper introduces the results of numerical solution of heat transfer problem in closed rectangular region in free convection using the conjugate heat transfer model. Gas infrared emitters arranged horizontally in upper part of simulation region have been considered as the heating source. Plane non-stationary problem was solved within the Navier-Stokes model for gas and heat transfer for solid boundaries. The dynamics of heat distribution in closed region with time was analyzed. It was ascertained that the most of heat is accumulated in enclosures affected by heat radiation. The authors made the conclusion on the stated model applicability for heat transfer calculation with radiation heating source. The paper demonstrates the possibility of using the potential of conjugate heat transfer theory when solving typical problems of heat power industry. |
