COUPLE-STRESS FLUID SATURATED ROTATING POROUS LAYER WITH INTERNAL HEAT GENERATION AND DENSITY MAXIMUM

The effect of internal heat generation and density maximum on the onset of convection in a couple-stress fluid saturated rotating porous layer is studied analytically, when porous medium is not in local thermal equilibrium (LTNE). Two-field model is used for the energy equations each representing the solid and fluid phases separately. The linear stability theory is based on normal mode technique. Galerkin method is used to find the eigen values of the problem. The effects of internal generation, rotation and conductivity ratio are determined. Received: March 12, 2023Accepted: July 4, 2023

期刊介绍： The JP Journal of Heat and Mass Transfer publishes peer-reviewed articles in heat and mass transfer which enriches basic ideas in this field and provides applicable tools to its users. Articles both theoretical and experimental in nature covering different aspects in the area of heat and mass transfer such as heat transfer in phase change phenomena, machinery and welding operations, porous media and turbulence are considered. Priority is given to those which employ or generate fundamental techniques useful to promote applications in different disciplines of engineering, electronics, communication systems, environmental sciences and climatology. Because a combination of two or more different technologies in a single device may result into a significant development, the journal extends its scope to include papers with the utility value in electronics and communication system. In this spirit, we are devoting certain number of issues to ‘Mechanical Systems and ICT – Convergence’. Survey articles dealing with certain issues in the context of current developments in heat and mass transfer together with their applications in interdisciplinary topics are also entertained.
