Table 1: Adopted Boundary Conditions - It was through the boundary conditions that the defined properties of the fluid will be calculated.


Boundary conditions

Inlet and top & bottom boundaries

Homogeneous velocity profile , with adjustable velocity components u and v as needed, and the component w with zero velocity.


Static pressure equal to 0 Pa, or gauge pressure equal to atmospheric pressure.


No-slip condition, impermeable wall, stationary wall.


Atmospheric air as the working fluid used with a constant density of 1.225 kg/m3 and a viscosity of 1.7894 × 10-5 kg/m·s
