Finite Element Analysis of Fluid Flow through the Screen Embedded between Parallel Plates with High Reynolds Numbers

Abstract

This paper provides numerical estimation of Newtonian fluid flow past through rectangular channel fixed with screen movable from 10° to 45° by increasing the Reynolds number from 1000 to 10,000. The two-dimensional incompressible Navier Stokes equations are worked out making use of the popular software COMSOL MultiPhysics version 5.4 which implements the Galerkin’s least square scheme to discretize the governing set of equations into algebraic form. In addition, the screen boundary condition with resistance coefficient (2.2) along with resistance coefficient 0.78 is implemented along with slip boundary conditions applied on the wall. We engaged to find and observe the relationship between the optimum velocity, drag force applied by the screen, and pressure occurred in the channel with increasing Reynolds number. Because of the linear relationship between the optimum velocities and the Reynolds number, applying the linear regression method, we will estimate the linear equation so that future prediction and judgment can be done. The validity of results is doing with the asymptomatic solution for stream-wise velocity at the outlet of the channel with screens available in the literature. A nondimensional quantity, i.e., ratio from local to global Reynolds number Re x / Re , is introduced which found stable and varies from -0.5 to 0.5 for the whole problem. Thus, we are in the position to express the general pattern of the velocity of the particles as well as the pressure on the line passing through the middle of the channel and depart some final conclusion at the end.

“…The analogy is that a replacement of the Prandtl number can be made with the Schmidt number when dealing with the mass transfer problems. Also, it is explained in the literature that your results will obtain an accuracy of 80% when you compare your results with the correlations 43 – 45 . Surely, we can also presage from our simulation that accuracy can be improved when the chemical reactions are performing at the lower velocities so that the diffusion of the mixture remains under control and better accuracy will be achieved.…”

On the Analysis of Power Law Fluid over a Diamond Shaped Cylindrical Surface with Screen Boundary Conditions at High Reynolds Number

“…A finite element method employing the least square technique of Galerkin's procedure is employed for power-law fluids within the non-Newtonian model, spanning the range from 0.8 to 1.2. Numerous research contributions related to this methodology have been published in reputable journals and conferences [30][31][32][33][34][35], with verification against the asymptotic solution illustrated in [36].…”

“…Moreover, the horizontal and vertical flow patterns were discussed in detail. Several linear regression lines [24] for optimum pressure and velocity in the rectangular domain and the drag force due to screen for in terms of the Reynolds number were expressed using the FEM approach with Galerkin's scheme. With the implementation of the screen boundary condition, another benchmark problem [25] for Newtonian and the non-Newtonian fluid using the power-law model of Oswald-de Waele was observed in the rectangular channel.…”
