Studies on CFD Analysis in Steam Nozzles - A Review

Abstract

The nozzle is a device that guides the steam to hit the moving or rotating blades and to convert one form of energy into another i.e., to convert the pressure energy into kinetic energy. Within the case of a small turbine. The nozzle designs are improved depending upon the application where it is used and the factors considered for the design of the system. To examine and understand the performance of different types of nozzles, numerical simulations are done in a analysis software known as fluent. In this review, a literature study was conducted related to temperature, pressure, density, velocity, and power output parameters. In addition, a summary was provided related to the performance of the nozzles in turbines.
