摘要：

In the present study, a novel methodology of 2D Direct Numerical Simulation (DNS), incorporating non-Boussinesq, inhomogeneous formulation with non-periodic boundary conditions is used to study the Rayleigh-Taylor Instability (RTI) of miscible fluid at the interface. The evolution of RTI is shown with density contours and mixing length. The system considered here is completely isolated and hence entropy evolution of the system reported here is relevant from non-equilibrium thermodynamics point of view.
