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…
Dynamics of spheroids in pressure driven flows of shear thinning fluids
Vishal Anand, Vivek Narsimhan
Particles in inertialess flows of shear thinning fluids are a model representation for several systems in biology, ecology, and micro-fluidics.In this paper, we analyze the motion…
A catalog of pressure drop, deformation profile and tube laws for slender hyperelastic tubes conveying Newtonian flow at steady state
Vishal Anand
Slender tubes constituted of hyperelastic materials undergoing large deformations and conveying inertialess flow of Newtonian fluids at steady state are a model representations of…
Peeling of linearly elastic sheets using complex fluids at low Reynolds numbers
Anirudh Venkatesh, Vishal Anand, Vivek Narsimhan
We investigate the transient, fluid structure interaction (FSI) of a non-Newtonian fluid peeling two linearly elastic sheets at low Reynolds numbers. Two different non-Newtonian fl…
Transient compressible flow in a compliant viscoelastic tube
Vishal Anand, Ivan C. Christov
Motivated by problems arising in the pneumatic actuation of controllers for micro-electromechanical systems (MEMS), labs-on-a-chip or biomimetic soft robots, and the study of micro…
On the Deformation of a Hyperelastic Tube Due to Steady Viscous Flow Within
Vishal Anand, Ivan C. Christov
In this chapter, we analyze the steady-state microscale fluid--structure interaction (FSI) between a generalized Newtonian fluid and a hyperelastic tube. Physiological flows, espec…
Revisiting steady viscous flow of a generalized Newtonian fluid through a slender elastic tube using shell theory
Vishal Anand, Ivan C. Christov
A flow vessel with an elastic wall can deform significantly due to viscous fluid flow within it, even at vanishing Reynolds number (no fluid inertia). Deformation leads to an enhan…
Non-Newtonian fluid--structure interactions: Static response of a microchannel due to internal flow of a power-law fluid
Vishal Anand, Joshua David, Ivan C. Christov
We study fluid-structure interactions (FSIs) in a long and shallow microchannel, conveying a non-Newtonian fluid, at steady state. The microchannel has a linearly elastic and compl…
On the Enhancement of Heat Transfer and Reduction of Entropy Generation by Asymmetric Slip in Pressure-Driven Non-Newtonian Microflows
Vishal Anand, Ivan C. Christov
We study hydrodynamics, heat transfer and entropy generation in pressure-driven microchannel flow of a power-law fluid. Specifically, we address the effect of asymmetry in the slip…
