Can Sound Waves be Slowed?
Amey Joshi
Dielectric fluids experience a striction force in the presence of an external electric field. Although the striction force on the entire body of the fluid is usually zero, it does…
Convection triggered by an electric field in a fluid heated from above
Amey S. Joshi
I consider a dielectric fluid heated from above and subjected to an electric potential difference between its top and bottom. I show that for a suitably chosen electric potential d…
Rayleigh-Taylor Instability in Viscoelastic Fluids
Amey Joshi
In this paper I analyze the onset of Rayleigh-Taylor instability between two linear viscoelastic fluids assuming that the perturbations at the interface are small. In the first hal…
Stress due to Electric and Magnetic fields in Viscoelastic Fluids
Amey Joshi
A clear understanding of body force densities due to external electromagnetic fields is necessary to study flow and deformation of materials exposed to the fields. In this paper, w…
Plane Poiseuille flow through a porous medium - an analytical solution
Amey Joshi
This paper develops a closed-form, analytical expression for the Darcy velocity of a Newtonian fluid flowing through a channel filled with a porous medium, bound by rigid walls and…
