Opis
Izvleček:The flow of an incompressible viscous fluid id considered. The velocity vorticity formulation of the Navier-Stokes equation is used. The kinematics equation is solved for boundary vorticity values using the Boit-Savart law. The solution of the kinetics equation for domain values is obtained by employing a macro element approach. Using macro elements enables simulations on dense meshes, since it substantially reduces the algorithm`s memory requirements. The developed numerical algorithm has been used to simulate laminar flow over a square cylinder in channel. Low Reynolds number steady state flow simulation as well as transient simulation at higher Reynolds number have been investigated. The results have been analysed in terms of velocity, vorticity and pressure field distribution in the wake of the cylinder.
