RISA Numerical Investigation of the Detachment of the Trailing Particle From a Chain Sedimenting in Newtonian and Viscoelastic Fluids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Particles sedimenting in a viscoelastic fluid form chains. It has been observed in experiments that, sometimes, the last particle in the chain gets detached. In this paper, we investigate this ...
Normal Stresses on the Surface of a Rigid Body in an Oldroyd-B Fluid
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this note we present a proof showing that the contribution from the extra stress tensor to the normal component of the stress on the surface of a moving rigid body in an incompressible ...
