The annular is constructed by the two concentric cylinders in which the inner cylinder can rotate along the tangential direction at a constant speed. A slip boundary condition will be imposed to vanish the viscous effect in the vicinity of the outer cylinder wall. Moreover, the rotating cylinder is kept at a hot temperature, and the outer one is at a cold temperature. A three-dimensional incompressible Navier Stokes and energy equations were carried in cylindrical coordinates. The simulation was observed using the emerging computational tool of COMSOL Multiphysics 5.6, which implements Least Square Galerkin's scheme of finite element method. The parametric study will be done by altering the speed of rotation of the inner cylinder from 1 to 4, volume fraction from 0.001 to 0.9, and the aspect ratio from 0.4 to 0.6 for a fixed Reynolds number of 35,000. The results will be displ...

We have employed the power-law model for shear thickening and shear thinning fluids with the high Reynolds number between 1000 and 10,000. The obstacle has been solved by putting in the Galerkin’s least square strategy of the finite element method and the procedure has been carried out utilizing the commercial software COMSOL Multiphysics. Various flow properties such as 'maximum flow rate' and 'pressure' have been discussed in the terms of the Reynolds number and also using the linear and quadratic regressions in order to establish the relationship between them for the future analysis. Moreover the impact of turning screen in the shape of increment in the maximum flow rate and pressure is checked in terms of Reynolds number and Satisfactory results are gaine...

The leading two-dimensional incompossible Navier-Stokes equations are solved by applying the finite element method with least square Galerkin’s scheme using the commercial software COMSOL MultiPhysics 5.4. In the first step, results are contrasted by measuring the stream-wise velocity at the exit wall of the channel with the asymptotic solution provided by Elder [1], which was built on the analysis of fluid flow through the single screen. In the 2nd step we are going to present the velocity contours with surface plot and pressure drop arrow plot in the whole domain vs the inclination of the screens. Finally, dragging forces are calculated at the three perforated plates in terms of angle. T...
