Sedimentation of spheroids in Newtonian fluids with spatially varying viscosity
Vishal Anand, Vivek Narsimhan
This paper examines the rigid body motion of a spheroid sedimenting in a Newtonian fluid with a spatially varying viscosity field. The fluid is at zero Reynolds number, and the vis…

Shape dynamics of nearly spherical, multicomponent vesicles under shear flow
Anirudh Venkatesh, Vivek Narsimhan
In biology, cells undergo deformations under the action of flow caused by the fluid surrounding them. These flows lead to shape changes and instabilities that have been explored in…

Linear stability of cylindrical, multicomponent vesicles
Anirudh Venkatesh, Aman Bhargava, Vivek Narsimhan
Vesicles are important surrogate structures made up of multiple phospholipids and cholesterol distributed in the form of a lipid bilayer. Tubular vesicles can undergo pearling i.e.…
