The creation based on the finite element study of the fluid flow through the two- dimensional channel rectangular shaped and fit escorted 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 -450 and 450. The two-dimensional incompressible Navier Stokes equations are discretizing by finite element based software 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 channel from 1 m/sec to 10 m/sec, the resistance and refraction coefficients are tested from 2 to 3 and 0.2 to 1 respectively. The consequences of maximum speed as well as pressure and mixed drag force of all the screens are reviewed by fixing refraction coefficient from 0.2 to 1 over the resistance coefficient from 2 to 3. The results are presented via the graph and tables and predicted the numerical expectations. The existing research work is checked out by matching stream-wise velocity taking place at the exit of the channel with the asymptomatic solution constituted by Elder [1959].
