Abstract:

This paper gives a review on CFD analysis of control valve. Control valve is most commonly used final control element to regulate material flow in a process, the quality of the product is depending on final control element. At different throttling condition of valve opening can be analyzed using ANSYS-CFD. Control valves such as globe valve, Right angle globe valve, Butterfly valve are analyzed using CFD. The stiction, positioner overshoot, non-linearity of flow characteristic, corrosion are the problems of control valve. The presence of non-linearities such as stiction, dead band and backlash in control valve limits the performance. Process industries as like pulp and paper mills, chemical industries etc in that stiction might be caused by an over tight valve stem seal, by sticky valve internals. So in some critical situation, the corrosion and the stiction of the valve which causes the waste of the product or gives the poor quality of the product, so there is need to be diagnose these type of problems and proper solution must be required. By considering the ideal condition, with the boundary conditions the analysis of the fluid characteristic can be observed.
