Numerical Simulation of a Multistage Radial Inflow Turbine

Volume 6: Turbomachinery, Parts A and B, 2006
Aerodynamic performances of a three–stage radial inflow turbine are investigated with numerical simulation. Detailed flow fields, flow patterns, such as secondary flows etc. in the radial turbine impeller are presented and discussed in this paper.

Applications and Performance Levels of Radial Inflow Turbines

SAE Technical Paper Series, 1964
<div class="htmlview paragraph">The radial inflow turbine has found wide application in turbochargers, but only limited application in small gas turbines. It is shown that, when applied within proper design boundaries, efficiencies equal to the best axial flow turbines are obtainable, and that the radial turbine has significant inherent cost ...

Optimum incidence angle in centrifugal pumps and radial inflow turbines

Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 1998
A theoretical method is presented for establishing the optimum incidence angle in outward- and inward-flow runners. Relative through-flow and eddy vortex are considered separately in order to examine their influence on the vane inlet conditions. The action of the counter-rotating vortex and of the blade camber is analysed and an algorithm is given for ...

Numerical Simulation of the Flow Through the Rotor of a Radial Inflow Turbine

Volume 1: Aircraft Engine; Marine; Turbomachinery; Microturbines and Small Turbomachinery, 1997
An existing Navier-Stokes solver to simulate the turbulent transonic flow using block-structured grids has been used to optimize the guide vanes of radial inflow turbines. The code has been extended to calculate the flow in the rotating parts of turbomachines and is now used to simulate the turbulent flow through the rotor of a radial inflow turbine.

Temperature distribution study in a cooled radial inflow turbine rotor

14th Aerospace Sciences Meeting, 1976
A numerical study to determine the temperature distribution in the rotor of a radial inflow turbine is presented. The study is based on the use of the finite element method in the three dimensional heat conduction problem. Different cooling techniques with various coolant to primary mass flow ratios are investigated.

Radial Inflow Expansion Turbines for Power Recovery

Journal of Energy Resources Technology, 1982
Performance data for single-stage, radial inflow, expansion turbines is presented in a manner to enable the process designer to quickly estimate the amount of power available from a process stream, the maximum effective pressure ratio and the temperature drop.

Unsteady Rotating Radial Load of a Single Stage Radial Inflow Turbine

Volume 2D: Turbomachinery, 2016
Radial inflow turbines with pivoting stator vanes are known to keep a high level of efficiency over a large flow range. This turbine type maintains a good efficiency level at reduced speed because the turbine wheel is not very sensitive to negative incidence.

An Investigation of the Flow Structure in the Radial Inflow Transonic Turbine

Volume 1: Symposia, 2015
Radial inflow turbines which are an important component of a turbocharger consist essentially of a volute, a rotor and a diffuser. Vaneless volute turbines, which have reasonable performance and low cost, are the most widely used in turbochargers for automotive engines.

A New Approach to Performance Mapping of Radial Inflow Turbines

Volume 2B: Turbomachinery, 2019
Abstract The performance of radial inflow turbines, and specifically of turboexpanders for oil & gas applications, has been traditionally described in terms of efficiency versus velocity speed ratio (U/C) and discharge flow coefficient (Q/N). Especially in the testing phase, this latter parameter has been often preferred to the angle
