Computational Fluid Dynamics

← Back to Domain-Specific Abstractions by Domain

3 domain-specific abstractions whose origin domain is Computational Fluid Dynamics.

• Explicit algebraic stress model — A turbulence closure that expresses Reynolds-stress anisotropy explicitly as an algebraic tensor function of local mean strain, rotation, and turbulence scales.
• Immersed boundary method — A fluid–structure interaction method coupling an Eulerian fluid grid to a moving Lagrangian structure through distributed force and velocity interpolation.
• Pressure-correction method — A class of numerical schemes coupling pressure and velocity in incompressible-flow computation by iteratively correcting a provisional velocity field.
