Computational Investigation of Incompressible Laminar Flow in T-type Channel Fixed with Circular Obstacle at The Center with No-slip Boundary Condition

Abstract

The present study of T-type channel inserted with circular obstacle with no-slip boundary conditions. The circular obstacle is fitted on the center, its role is to divert fluid towards two outlets calculating the impact of circular obstacle on fluid, and also applied her finite element model(FEM), with basic governing equations known as Navier-Stoke equation and continuity equation in COMSOL MultiPhysics with the range of Reynolds numbers Re=01 to Re=2000. Analyze the effect of circular obstacle increasing Reynolds number on magnitude of velocity, streamline pattern, formation of vortex and impact of pressure on Junction type channel. Numerical analysis of T-type junction with circular obstacle and outlets of the channel and effect of surrounding region of the obstacle, and effect of pressure on two outlet and different wall of the T-type junction, the present investigation is very important in Biomedical and Engineering filed, such as mixing of fluids, cooling of different type of fluid, blood flow in arties, heat flow with obstacle.
