2.1.4. Solution Algorithm

The phase coupled Semi-Implicit Method for Pressure Linked Equations (SIMPLE) method is used for the pressure–velocity coupling, and the Green–Gauss cell-based method is used to discretize the gradient. The equation of momentum, the particle temperature equation, the turbulent kinetic energy, and the dissipation rate equation are treated with the second-order upwind scheme. The Quadratic Upstream Interpolation for Convective Kinetics (QUICK) scheme is used to discretize the volume fraction equation.
