Abstract :
In this chapter, the flow is analyzed on a circular cylinder in a two-dimensional field. Since in many heat exchangers the flow is slow and incompressible fluid, this assumption is used and on the other hand due to the infinite assumption The length of the pipes to solve the incompressible fluid flow is analyzed in a two-dimensional field. The solution method is the numerical method of finite element and in this regard two points are important: Accuracy of problem solving plays a big role. Hydraulic cylinders convert the fluid flow under pressure into linear motion of the piston rod and are available in single and double types. In the one-job type, the return to the original position is done by a spring or gravity force, but in the two-job type, the return operation is performed under the control of hydraulic fluid. In this dissertation, a cylinder with a circular cross section under the angle of attack relative to the flow is studied numerically. The two-dimensional flow model is incompressible and, assuming the flow is viscous, the Navira-Stokes equations are used for field analysis. The purpose of this dissertation is to investigate the qualitative and quantitative effect of pressure analysis on a cylinder at a specific angle of attack.
