Numerical Analysis of the Effects of Different Rotor Tip Gaps in a Radial Turbine Operating at High Pressure Ratios Reaching Choked Flow

Galindo, José; Tiseira, Andrés-Omar; Navarro, Roberto; Inhestern, Lukas Benjamin; Echavarria-Olaya, Juan David (MDPI AG, 2022-12)

[EN] To operate, radial turbines used in turbochargers require a minimum tip gap between the rotor blades and the stationary wall casing (shroud). This gap generates leakage flow driven by the pressure difference between ...
Numerical Analysis of the Effects of Grooved Stator Vanes in a Radial Turbine Operating at High Pressure Ratios Reaching Choked Flow

Galindo, José; Tiseira, Andrés-Omar; Navarro, Roberto; Lukas Benjamin Inhestern; Echavarria-Olaya, Juan David (MDPI AG, 2023-04)

[EN] The flow through the stator vanes of a variable geometry turbocharger turbine can reach supersonic conditions and generates a shock wave on the stator vanes, which has a potential impact on the flow loss as well as ...
Potential of using a nozzle at the compressor inlet of a high-speed direct-injection diesel engine

Desantes, J.M.; Luján, José M.; Plá Moreno, Benjamín; Soler Muniesa, José Antonio (SAGE Publications, 2011)

[EN] The present work reports the effect of a nozzle placed upstream of the compressor of a high-speed direct-injection diesel engine. It has been observed that mounting a nozzle at the compressor inlet can lead to a shift ...
