Viscous flow past plates
… of high order in space (FDMHS) to simulate flow past a finite plate and a semi-infinite plate. The method solves the incompressible Navier-Stokes equation in the stream function-vorticity formulation. The focus is to study a fundamental problem in fluid dynamics, namely, flow past sharp …

Dynamics of semi-flexible fibres in viscous flow
The dynamics of semi-flexible fibres in shear flow and the effect of flexibility on the swimming speed of helical flagella are investigated. High aspect ratio particles such as carbon and glass fibres are often added as fillers to processed polymers. Although these materials have high rigidity, the …

Stability of Viscous Flow Past a Rotating Cylinder
… an otherwise quiescent fluid (i.e., with no mean flow). The existence of such three-dimensional steady flows would explain the observations of Jaminet and Van Atta that the flow in the wake of a rotating cylinder is steady at high alpha.

Adaptive finite element simulation of incompressible viscous flow
… two- and three-dimensional incompressible flows. The formulation is based on a segregated solution method. In this segregated formulation, the velocities and pressures are uncoupled and the equations for each are solved one after the other. This segregated solution method is numerically …
