DD::Fluid::Solver::SolverFire

We required a simulator which could produce complex and turbulent flames. Artifacts such as flame sheet separation, or multiple flame interactions, are difficult to produce with single-phase incompressible Navier-Stokes solvers. We chose to employ the multi-phase fire simulation scheme introduced by Nguyen et al [2002]. The reacting vaporized fuel, or blue core, is simulated like a liquid, and tracked with a particle corrected level set surface. Temperatures and densities are generated around the blue core to drive the gaseous phase. The two phases are modelled separately, and subsequently coupled by enforcing mass and momentum conservation.
