Penetrative ferroconvection in a heterogeneous Brinkman porous medium

M. Ravisha et al.

Summary: This study aims to find the linear theory for the onset of ferromagnetic convective flow in a heterogeneous Brinkman porous layer with uniformly distributed internal heat source in the presence of a vertical magnetic field. Numerical results show that the type of vertical heterogeneity permeability function and N-s parameter can either delay or speed up the flow of ferrofluids. Additionally, the critical Rayleigh number increases with increasing Da but decreases with increasing R-m and M-3 for different forms of the permeability function. Furthermore, isothermal boundaries are more stabilizing compared to insulated boundaries.

R. Naveen Kumar et al.

Summary: This study discusses the flow of a ferromagnetic viscous liquid with thermophoretic particle deposition over a stretching cylinder, taking into account a uniform heat source/sink parameter.
