The College of Science in the Department of Mathematics discussed a seminar entitled Double diffusive convection in bidispersive porous media with couple stresses effect and relatively large macropores for postgraduate student Zaid Abbas Afluk , The seminar aims to investigate the problem of double-diffusive convection in a porous medium that exhibits bidispersive characteristics and how it influenced by coupled stresses. The model employed incorporates the Darcy theory in the micropores while utilizing the Brinkman theory in the macropores
