My PhD research specialised in conjugate heat and mass transfer within both plain and porous media. I focused on complex fluid dynamics, including magneto-hydrodynamic (MHD) free convection and double-diffusive flow in radiative participating mediums. By developing in-house numerical codes, I solved intricate conjugate problems using finite-volume methods (FVM) for hydrodynamics and the Discrete Ordinates Method (DOM) for radiative transfer. My work also extended to the study of non-Newtonian flows across various plain and porous composite configurations.
