Simulation of a Turbulent Impinging Jet into a Layer of Porous Material Using a Two–Energy Equation Model

摘要: This article presents numerical results for a turbulent jet impinging against flat plane covered with layer of permeable and thermally conducting material. Distinct energy equations are considered the solid porous material attached to wall fluid that impinges on it. Parameters such as Reynolds number, porosity, permeability, thickness, thermal conductivity varied in order analyze their effects local distribution Nu. The macroscopic mass, momentum, obtained based volume-average concept. technique employed discretizing governing was control volume method boundary-fitted nonorthogonal coordinate system. SIMPLE algorithm used handle pressure-velocity coupling. Results indicate inclusion eliminates peak Nu at stagnation region. For highly material, simulations integral heat flux ...
