External Flow Passing Through a Flat Plate, ANSYS Fluent CFD Training
https://www.mr-cfd.com/shop/external-...
The present problem simulates the external flow of air passing through a flat plate by ANSYS Fluent software. The operating fluid used in the simulation process is air, which has a density of 1.225 kg.m-3, a viscosity of 0.000017894 kg.m-1.s-1 and a thermal conductivity of 0.0242 Wm-1.K -1. The model is two dimensional; So that the lower edge of the model represents the plate and the two vertical edges on the left and right of the model are equivalent to the inlet and outlet of the air flow. The plate temperature is assumed to be a constant value of 333 K and the free air flow temperature is assumed to be 273 K.
The flow is also of the laminar type because the definition values for the Reynolds number are less than the critical Reynolds in the case of external flows on a plate. The values of the defined Reynolds are equal to 10,000, 20,000, 30,000, 40,000, and 50,000, respectively, which will determine the amount of incoming air velocity according to the relation related to the Reynolds number. The purpose of the problem is to study the airflow behavior on a plate and to investigate the velocity and temperature distributions as well as the hydrodynamic boundary layer.
