Design and Modeling of Wye Piece

Abstract

Penstocks are an important component in hydropower plant projects especially when there is a high head turbine need to plant. These must design to withstand high-pressure under static as well as transient conditions. In this paper, we discuss the static stress analysis of internal water pressure in a penstock wye piece and we came to the conclusion that by the addition of concrete and rock to the steel pipe the maximum von Mises stress is well below their respective yield stress.
