What is Multiphysics Fluid Dynamics?
In the engineering and science fields, the equations that govern a process often have a 'multiphysics' nature, meaning that:
- Coupled quantities: Several quantities are interdependent, obeying transport equations that must be solved concurrently (e.g., exothermic reactions occurring in a flowing gas containing a number of chemical species);
- Nonlinear equations: The transport equations contain varying and/or nonlinear coefficients, often in the diffusion or source terms (e.g., non-Newtonian fluid flow or systems that involve temperature dependent material properties);
- Multiphase/fluid: There may be multiple fluid types and phases present (e.g., a single gas bubble rising within a liquid, or the sedimentation of sand within oil); or
- Multiple geometries: The simulation domain is split between a number of coupled regions, each of which may have different dimensions or different interdependent quantities to be found.
