Design of an Annular-Radial Diffuser for Operation With a Supercritical CO2 Radial Inflow Turbine
Journal of Engineering for Gas Turbines and Power, 2019Radial inflow turbines are a relevant architecture for energy extraction from supercritical CO2 power cycles for scales less than 10 MW. To ensure stage and overall cycle efficiency, it is desirable to recover exhaust energy from the turbine stage through the inclusion of a suitable diffuser in the turbine exhaust stream.

Optimum incidence angle in centrifugal pumps and radial inflow turbines
Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 1998A 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 ...

Radial Inflow Expansion Turbines for Power Recovery
Journal of Energy Resources Technology, 1982Performance 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.

Numerical Simulation of the Flow Through the Rotor of a Radial Inflow Turbine
Volume 1: Aircraft Engine; Marine; Turbomachinery; Microturbines and Small Turbomachinery, 1997An 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, 1976A 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.

Unsteady Rotating Radial Load of a Single Stage Radial Inflow Turbine
Volume 2D: Turbomachinery, 2016Radial 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, 2015Radial 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.

Navier-Stokes Computation of Radial Inflow Turbine Distributor
Journal of Fluids Engineering, 1988A two-dimensional flow analysis of a radial inflow turbine distributor using full steady-state Reynolds-averaged Navier-Stokes equations is made. The numerical prediction of the total energy loss and the wicket gate torque is compared with experimental data.

A New Approach to Performance Mapping of Radial Inflow Turbines
Volume 2B: Turbomachinery, 2019Abstract 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

Design and Numerical Simulation of Radial Inflow Turbine Volute
International Journal of Turbo & Jet-Engines, 2014AbstractThe volute of a radial inflow turbine has to be designed to ensure that the desired rotor inlet conditions like absolute Mach number, flow angle etc. are attained. For the reasonable performance of vaneless volute turbine care has to be taken for reduction in losses at an appropriate flow angle at the rotor inlet, in the direction of volute ...
