Turbidity currents and pyroclastic density currents may originate as stratified flows or develop stratification during propagation. Analogue, density-stratified laboratory currents are described, using layers of salt solutions with different concentrations and depths to create the initial vertical stratification. The evolving structure of the flow depends on the distribution of the driving buoy...

In this paper a numerical investigation on the double diffusive natural convection in finned solar still is performed using finite volume method. The 3D vector potential-vorticity formalism used to eliminate gradient pressure terms and due complex shape of cavity blocked-off-region method adopted. After getting dimensionless governing equations, they are written generalised form then discretise...

mhd boundary layer flow of two phase model nanofluid over a vertical plate is investigated both analytically and numerically. a system of governing nonlinear partial differential equations is converted into a set of nonlinear ordinary differential equations by suitable similarity transformations and then solved analytically using homotopy analysis method and numerically by the fourth order rung...

[1] This study describes a satellite‐based method to estimate simultaneously convective buoyancy (B) and entrainment rate (l). The measurement requirements are cloud‐top height (CTH), cloud‐top temperature (CTT), cloud profiling information (from radar and lidar), and ambient sounding. Initial results of the new method applied to A‐ Train data are presented. It is observed that tropical oceanic...

We present a numerical study of vorticity production and transport in the two-dimensional Rayleigh–Bénard (RB) convection. Direct simulations are carried out Rayleigh number (Ra) range 105≤Ra≤106, Prandtl (Pr) 0.71, aspect ratio (Γ) convection cell 0.75≤Γ≤6. found that flow structure temperature distribution vary with Γ greatly due to multiple vortices interaction. Further investigation on reve...
