The PISO (Pressure Implicit with Splitting of Operators) is an efficient method to solve the Navier-Stokes equations in unsteady problems. The main differences from the SIMPLE algorithm are the following[1]: No under-relaxation is applied. The momentum corrector step is performed Continue reading pisoFOAM→

Incompressible Viscous Turbulent Heat Transfer Energy Equation

Posted on Friday, August 20, 2010 by Martin — No Comments ↓

Generally, incompressible viscous turbulent heat transfer energy equation is [latex]\dfrac{\partial T}{\partial t} + \nabla\cdot(\boldsymbol{U} T) = \alpha \nabla^2 T + \dfrac{\nu}{c_\mathrm{p}} [\nabla \boldsymbol{U} +(\nabla \boldsymbol{U})^\mathrm{T}]:\nabla \boldsymbol{U} [/latex] ddt(T) + div(U T) = alpha laplacian(T) + ((nu/cp (grad(U) + (grad(U)).T)) && Continue reading Incompressible Viscous Turbulent Heat Transfer Energy Equation→
