Decelerating Inclined Thermals with Suspended Solid Particles

Flows with suspended and floating particles

The evolution of the configuration of a set of particles dispersed in a flowing liquid is crucial in many applications such as sedimentation, slurry transport, rheology and structured arrays of micro and nano particles. Direct Simulation based on what is called Fictitious Domain Method coupled with Finite Element Method has been used to study particulate flows and sedimentation process. Here we...

Thermals in contact binaries

The buoyant rise of thermals (i.e. bubbles of enhanced entropy, but initially in pressure equilibrium) is investigated numerically in three dimensions for the case of an adiabatically stratified layer covering 6–9 pressure scale heights. It is found that these bubbles can travel to large heights before being braked by the excess pressure that builds up in order to drive the gas sideways in the ...

A direct simulation method for flows with suspended paramagnetic particles

A direct numerical simulation method based on the Maxwell stress tensor and a fictitious domain method has been developed to solve flows with suspended paramagnetic particles. The numerical scheme enables us to take into account both hydrodynamic and magnetic interactions between particles in a fully coupled manner. Particles are assumed to be non-Brownian with negligible inertia. Rigid body mo...
