报告摘要：Electrical appliances and electronic devices with compact designs are trending nowadays. However, there is always a drawback for electronic devices is the heat generation during operation, in which excessive heat generated might lead to malfunction of the device or even worse. Hence, developing electronics with high performance and yet effective cooling is crucial. Therefore, understanding the phenomena of fluid flow and heat transfer processes in enclosures is important in many engineering and industrial applications, as most electrical appliances and electronic devices are confined within their outer container. The geometry of the system, that is, the shape and size of the enclosure and boundary wall temperatures, can be the factors that provide optimal heat transfer for various engineering applications. Hence, the effects of the enclosure’s shape and aspect ratio will be the subjects of the present study. A porous enclosure filled with fluid is considered. The enclosure’s left side wall is heated at a higher temperature while the right side wall is cooled at a lower temperature. The top and bottom walls are insulated. The governing equations and boundary conditions are derived from the proposed physical model. The governing system of partial differential equations is non-dimensionalized, using suitable dimensionless variables to reduce the complexity of physical quantities involved in solving the system. An appropriate numerical algorithm is developed to find the numerical solutions of heat transfer and fluid flow in the enclosures. This study will provide new understanding and algorithms that benefit engineering application designs.
