Wadile, Prasad P (2015) Numerical Study of Laminar Natural Convection in an Enclosure with Conjugate Heat Transfer. MTech thesis.
The study of a laminar natural convection in a square enclosure with conjugate boundary condition is done numerically. The top wall and right side wall of the enclosure are considered to have some finite thickness. The problem is solved using finite volume method and the multi-block method is used for meshing the domain. Various cases are considered by varying the parameters like characteristics Reynolds number, conductivity ratio and the wall thickness to analyse their effect on the heat transfer and flow characteristics. Reynolds number is taken equal to 10e3, 5 * 10e3 and 10e4 to constrain the flow as laminar in enclosure. The result shows some significant dependence on Reynolds number in the flow and temperature field inside the domain. An effect of insulation near the top wall is also studied and compared with the case of without insulation by varying the same parameters. It is to be noted that the average temperature inside the enclosure is reduced considerably due to the insulation.
