RISImpulse Turbine Injector Design Improvement Using Computational Fluid Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study utilizes two modern computational fluid dynamics (CFD) software packages (ansysآ®cfxآ® and ansysآ®fluentآ®) to analyze the basic geometric factors affecting the efficiency of a typical impulse turbine injector. ...
Numerical Investigation of the Spear Valve Configuration on the Performance of Pelton and Turgo Turbine Injectors and Runners
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper uses two modern commercial cfd software packages to compare the performance of a standard and improved impulse turbine injector developed in a previous study. The two injector designs are compared by simulating ...
Out With the Old, in With the New: Pelton Hydro Turbine Performance Influence Utilizing Three Different Injector Geometries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In previous works, the authors presented computational fluid dynamics (CFD) results, which showed that injectors with noticeably steeper nozzle and needle tip angles 110 deg & 70 deg and 150 deg & 90 deg, respectively, ...
