It is well known that when a fluid is thermally unstable, convection can be the most efficient mechanism for mixing and energy transport. However, the presence of a stable composition gradient can counteract and inhibit convection, giving rise to an interesting phenomenon called double-diffusive convection - or semi-convection - which is characterized by layers of convective and diffusive zones. In this seminar, I will discuss some of the main properties of semi-convection and its relevance to gas giant planets. Finally, I will show 2D hydrodynamical simulations of this process. https://astronomia.uc.cl/2jucext1/institutoastrofisica/es/instituto/seminarios/evento/357-hydrodynamics-of-double-diffusive-convection-jose-rafael-fuentes-mcgill-university
