Hi,
I want to simulate a standard laminar flow problem using comsol. This problem is being for validating Comsol. The 2D pipe geometry is 0.2 m dia and 8 m length. The flow is laminar flow. Velocity is 1 m/s.
The density of the pipe is 1 kg/m^3 and viscosity mu is 0.002. So, Re = 100 < 2300.
The maximum velocity for parabolic profile shall be 2x1=2 m/s but after solving the velocity is coming 1.49 m/s. In what way the modelling shall be performed so that the desired results can be simulated in a stard format not as hit and trial method.
I have taken one side of width as inlet and other side as outlet. The other two longitudinal dimensions are taken as wall with no slip condition. Poutlet = 0 and 101325 Pa for two different cases.
Kindly help me modelling this problem.
Thanks.
