Turbulence viscosity: ${\mathrm{\μ}}_t=\mathrm{\ρ}{C}_{\mathrm{\μ}}\frac{k^2}{\mathrm{\ϵ}},$

K equation: $\mathrm{\ρ}\frac{\∂k}{\∂t}+\mathrm{\ρ}{u}_j\frac{\∂k}{{\∂x}_j}=\frac{\∂}{{\∂x}_j}\left[(\mathrm{\η}+\frac{{\mathrm{\η}}_t}{{\mathrm{\σ}}_k})\frac{\∂k}{{\∂x}_j}\right]+{\mathrm{\η}}_i\frac{{\∂u}_i}{\∂x_j}(\frac{{\∂u}_i}{{\∂x}_j}+\frac{{\∂u}_j}{{\∂x}_i})-\mathrm{\ρ\ϵ},$

ε equation: $\mathrm{\ρ}\frac{\∂\mathrm{\ϵ}}{\∂t}+{\mathrm{\ρu}}_k\frac{\∂\mathrm{\ϵ}}{{\∂x}_k}=\frac{\∂}{{\∂x}_k}\left[(\mathrm{\η}+\frac{{\mathrm{\η}}_t}{{\mathrm{\σ}}_{\mathrm{\ϵ}}})\frac{\∂\mathrm{\ϵ}}{{\∂x}_k}\right]+\frac{c_1\mathrm{\ϵ}}{k}{\mathrm{\η}}_t\frac{{\∂u}_i}{{\∂x}_j}(\frac{{\∂u}_i}{{\∂x}_j}+\frac{{\∂u}_j}{{\∂x}_i})-c_2\mathrm{\ρ}\frac{{\mathrm{\ϵ}}^2}{k},$
