A sharp interface immersed boundary method for compressible viscous flows

An immersed boundary method for computing viscous, subsonic compressible flows with complex shaped stationary immersed boundaries is presented. The method employs a ghost-cell technique for imposing the boundary conditions on the immersed boundaries. The current approach leads to a sharp representation of the immersed boundaries, a property that is especially useful for flow simulations at high...

Interaction of two deformable viscous drops under external temperature gradient

The axisymmetric deformation and motion of interacting droplets in an imposed temperature gradient is considered using boundary-integral techniques for slow viscous motion. Results showing temporal drop motion, deformations and separation are presented for equal-viscosity fluids. The focus is on cases when the drops are of equal radii or when the smaller drop trails behind the larger drop. For ...

Boundary Integral Equations for Viscous Flows - non-Newtonian Behavior and Solid Inclusions

Direct boundary integral formulations are developed for the solution of viscous fluid flow problems, specifically for non-Newtonian fluids and fluids containing solids. The partial differential equations are transformed into integral equations by Green’s identities. Here, the velocity field is represented as a combination of hydrodynamic potentials of singleand double-layer, whose densities are...

Boundary Layer Meshing for Viscous Flows in Complex Domains

High reynolds number ow simulations exhibit strong gradients normal to walls and across shear layers requiring much ner resolution of the solution in some directions compared to others. To keep mesh sizes manageable for such problems, meshes with highly anisotropic elements are necessary. In this paper, a method for generating boundary layer meshes for arbitrarily complex non-manifold geometric...

The Ghost Fluid Method for Viscous Flows

Abstract: The level set method for compressible flows [13] is simple to implement, especially in the presence of topological changes. However, this method was shown to suffer from large spurious oscillations in [11]. In [4], a new Ghost Fluid Method (GFM) was shown to remove these spurious oscillations by minimizing the numerical smearing in the entropy field with the help of an Isobaric Fix [6...
