To study the flow topology and temperature distribution of Rayleigh-Benard convection in a highly slender cell, measurement simultaneous velocity 3-D domain is required. For this aim, implementing time-resolved PTV two-colour PLIF planned. As part development, for both techniques, experimental setup has been implemented separately to measure 2-D presented paper. PTV, scanning system also utiliz...

A numerical study on the Rayleigh–Benard convection in a shallow cavity filled with different metal-oxide water-based nanofluids is presented through two-phase model, which accounts for effects of Brownian diffusion and thermophoresis, at variable properties temperature. Numerical simulations are executed values average volume fraction nanoparticles, aspect ratios enclosure, as well temperature...

The onset of convection in a rotating plane layer due to vertical temperature gradient is studied this paper. background stratification modulated by lateral variations and stable aimed at understating the Earth's outer core subject thermal core–mantle interaction. At top boundary, sinusoidal Gaussian are imposed apart from reference case isothermal condition used classical Rayleigh–Benard conve...

An investigation is carried out to determine the effect of uniform and non-uniform temperature profiles on single component Darcy-Benard Marangoni (DBM) convection in a composite layer system consisting an incompressible fluid saturated porous top which same with variable heat sources both layers. The upper surface free tension effects depending lower rigid. eigen value, thermal number (TMN) so...

Onset of Double Diffusive Rayleigh-Benard-Magneto (DDRBM) convection is studied for a double layered system composed incompressible fluid confined by adiabatic rigid peripheries under the governance Local Thermal Non-Equilibrium (LTNE). Result acquired problem obtained analytically through mode Regular Perturbation. Consequence physical factors such as solid phase thermal expansion ratio, diffu...
