The circle of turbine stationary vanes that convert pressure and thermal energy to velocity energy and direct the combustion gases in the direction of turbine wheel rotation is referred to as what?
• Gas turbine basic components: compressor, combustor, turbine, diffuser • Function of stationary vs. rotating turbine parts • How nozzles and diffusers affect fluid velocity and pressure
• Which component’s job is to take high-pressure, high-temperature gas and turn it into high-velocity flow directed onto the turbine blades? • Among the options, which one is made up of stationary vanes rather than rotating blades? • What does a diffuser do to fluid velocity and pressure, and is that the same as what’s described in the question?
• Identify which option is specifically associated with stationary vanes around the turbine wheel • Confirm which component increases gas velocity and aims it in the direction of wheel rotation • Eliminate any option whose main purpose is to slow the flow and increase pressure rather than increase velocity
