Turbocharger Axial Turbines for High Transient Response, Part 1: A Preliminary Design Methodology

open access: yesApplied Sciences (Switzerland), 2019
This paper proposes a preliminary design algorithm for application of a turbocharger axial turbine, based on turbine thermodynamic analysis and the Ainley-Mathieson performance model that converges to the optimal design based on a set of input parameters

Conceptual Design of an Axial Turbocharger Turbine

Volume 8: Microturbines, Turbochargers and Small Turbomachines; Steam Turbines, 2017
Despite engine turbocharging being a widespread technology, there are still drawbacks present in current turbocharging systems stemming from the apparent mismatch between the periodic operation of a piston engine operating in conjunction with an essentially steady-state, rotordynamic machine (turbocharger).

The Axial Flow Turbine

1982
In the early days of turbochargers, axial flow turbines were used exclusively, assisted by experience gained from aircraft gas turbine technology after 1945. Indeed, it was largely turbine blade material developments, pioneered for gas turbines, that made diesel engine turbochargers practicable.

Axial Compressors and Turbines

2012
With the definition of the work coefficient in (6.4a) and (6.4b), we can now write from (4.22a) to (4.22d) the nondimensional azimuthal velocity component expressions as follows: $$ \frac{{{{c}_{\rm{u1}}}}}{u} = \left( {1 - \hat{r}} \right) - \frac{\Psi}{4} $$ $$ \frac{{{{c}_{\rm{u2}}}}}{u} = \left( {1 - \hat{r}} \right) + \frac{\Psi}{4} $$

Secondary Flows in Axial Turbines—A Review

Annals of the New York Academy of Sciences, 2001
Abstract: An important problem that arises in the design and the performance of axial flow turbines is the understanding, analysis, prediction and control of secondary flows. Sieverding1 has given a review of secondary flow literature, covering up to 1985.
