To Optimize Model of Elbow Draft Tube for Maximizing Efficiency

In this research our main objective is to design a elbow draft tube with varying diffuser angle and to find out the optimized model for the same or with enhanced diffuser angle. In order to enhance the design methodology as compare to the conventional draft tube design , we are adopting the simulation method to resolve the problem of draft tube design and to reduce the cost of prototyping and to get the improved results by using computational fluid analysis in ANSYS 14.0 by CFX solver. Aim is to be maximizing the pressure in the outlet of the draft tube. We have to take one factor to optimise the model of elbow draft tube in hydro power plant. The base paper experimental values are taken. Analysing of pressure and velocity contour in the previous results and our results will validate. The pressure contour and velocity contour taken are different diffuser angle.
