| Summary: | A 2-D flow of incompressible fluid is considered. The flow is uniform and
disturbed by a cylinder. The flow will be modelled based on the assumptions
which are irrotational inviscid fluid and rotational viscous fluid. For irrotational
and inviscid model, the flow will be modelled by Laplace equation of
stream function and Bernoulli equation for pressure. For rotational and viscous
model, the flow will be modelled by Poisson equation of stream function
coupled with transport equation of vorticity. The model is solved numerically
by a finite difference method to observe streamlines, velocity vector, pressure
and the contour of vorticity function around the cylinder. For the rotational
and viscous model, we found that the model depends on the Reynold’s number
involved in the model. For small Reynold’s number, the streamlines are
confirmed to be laminar flow. |
