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
OpenFOAM is one of the most famous open-source CFD toolbox, which current version is 1.6. In this version, there are some aspects changed, like: solver syntax, time-dependent vector boundary, integrating some flow models. Here, I will show you how to Continue reading Time-Dependent Vector Boundary Conditions in OpenFOAM
