The major considerations in the design of effective methods for computational aerodynamics are the capability to treat flows over complex geometrical shapes with proper representation of shock waves, discontinuities and viscous effects.
The methods of kinematic wave and discontinuity analysis are applied to problems of boilup with foam formation.
We present a sharp interface approach which treats the interface as a shock-wave like discontinuity.
By extending the CFM to this new class of PDEs, the treatment of wave interface discontinuities in homogeneous media becomes possible.
Its capability to properly handle low Mach number unsteady flows, that may include acoustic waves or discontinuities, is numerically illustrated.
A relatively wide spectrum of detection functions (sensors) is employed for representative flow cases which include boundary layers, vortices, jets, wakes, shock waves, contact discontinuities, and expansions.
The Ulysses mission goes to the polar regions of the heliosphere and therefore is an ideal mission to study Alfvén waves and discontinuities.
We analyze the magnetic field data of Ulysses during the mission to study the waves and discontinuities in the heliosphere at different locations, covering a total sunspot cycle.
A computational approach for modeling interactions between shocks waves, contact discontinuities and reactions zones with a high-order compact scheme is investigated.
A classich-refinement adaptive procedure is implemented to increase the spatial resolution of high-speed unsteady flow characteristics such as shock waves, contact discontinuities, or expansion waves with minimal computational costs and memory overheads.
