in this paper, the combined effect of suspended (fine dust) particles and rotation on the onset of thermosolutal convection in an elastico-viscous fluid in a porous medium is studied. for the porous medium, the brinkman model is employed and rivlin-ericksen model is used to characterize viscoelastic fluid. by applying normal mode analysis method, the dispersion relation has been derived and sol...

A layer of fluid lies between two parallel horizontal walls and the solute concentration and temperature are higher at the bottom wall. The onset of time-periodic instability in this double diffusion problem in three dimensions is analyzed. Periodicity with respect to the hexagonal lattice is assumed. The no-slip condition is imposed at the top and bottom boundaries. There are 11 bifurcating so...

In this work, we proposed a diffuse interface model for the dendritic growth with thermosolutal convection. model, sharp boundary between fluid and solid dendrite is replaced by thin but nonzero thickness interface, which described order parameter governed phase-field equation growth. The governing equations solute heat transfer are modified such that previous special treatments source term can...

The present study investigates the effect of mass transpiration on heat absorption/generation, thermal radiation and chemical reaction in magnetohydrodynamics (MHD) Darcy–Forchheimer flow a Newtonian fluid at thermosolutal Marangoni boundary over porous medium. region consists H2O as base fractions TiO2–Ag nanoparticles. mathematical approach given here employs similarity transformation, order ...

Thermosolutal convection in a square cavity filled with air and submitted to an inclined magnetic field is investigated numerically. The cavity is heated and cooled along the active walls with a mass gradient whereas the two other walls of the cavity are adiabatic and insulated. Entropy generation due to heat and mass transfer, fluid friction and magnetic effect has been determined in transient...

A layer of compressible, rotating, elastico-viscous fluid of related density heated & soluted from below is considered in the presence of vertical magnetic field to include the effect of Hall currents. Dispersion relation governing the effect of visco-elasticity, salinity gradient, rotation, magnetic field and Hall currents is derived. For the case of stationary convection, the Rivlin-Erickson ...
