Abstract :
The present studybased on applying the finite element’s methodology to analyze the fluid flow through the two-dimensional channel rectangular shaped andescorted by the three blocks imposing with screen boundary conditions on them. These blocks or screens are affixed at unit distance from each other with two different angles -450and 450. The two-dimensional incompressible Navier Stokes equations are discretizing by finite element-basedsoftware COMSOL MultiPhysics 5.4 which embraced the Galerkin's least square operation. The air is working fluid which endures to enter from the exit of the channelwith the average velocities of1 m/sec to 10 m/sec, the resistance and refraction coefficients are tested from 2 to 3 and 0.2 to 1 respectively.Theobjectiveof thestudytoanalyzethemaximumvelocityand the maximum pressure when thefluidenterstheregionwhichcomprises three screens inclined at angles by enhancing the resistancecoefficientby fixing refraction coefficient.
