Transient Response of Mixed Flow Variable Geometry Turbine for a Turbocharger
TL;DR: In this paper, a specific design of mixed flow variable geometry turbine for an automotive sub 1.5 litre diesel engine turbocharger is proposed, and an experimental set up is developed for measuring the steady state and transient response behaviour of the turbine at different nozzle vane opening positions.

Dual-output PID transient control of an electric-assisted air charge system
TL;DR: In this article , an external electric compressor (eBoost) is added to a turbocharged, large displacement diesel engine to significantly reduce turbo-lag, along with a bypass valve, and a dual-output PID controller is proposed for controlling the boost pressure using the VGT and eBoost.

An evaluation method for transient response performance of a turbocharger in gasoline engine: Simulation and experiment
TL;DR: In this article , an explicit relationship between key thermodynamic parameters of turbine and compressor and the evaluation index of D x that can characterize turbocharger transient response are established. And the proposed evaluation method is tested and verified using the coupling between GT-Power and MATLAB Simulink software based on the gasoline turbochargers.

Ahmed Ketata,Zied Driss +1 more
TL;DR: In this paper , the effect of the working gas on the performance of turbocharger turbines as well as on the turbo lag was investigated through a set of numerical simulations for six wastegate opening degrees from 0% up to 100% and under a wide range of the flow pulse frequency ranging from 33.33 up to 166.66

Mixed-flow turbines for automotive turbochargers: Steady and unsteady performance
TL;DR: In this article, the steady and unsteady performances of a mixed-flow turbocharger turbine with a constant blade inlet angle have been investigated, and the results indicated that the mixed flow turbine obtains a peak efficiency (total-to-static) of 75 per cent at a velocity ratio of 0.61, compared with that of a typical radial-inflow turbine which peaks at a high velocity of 1.7.

Mixed Flow Turbines: Inlet and Exit Flow Under Steady and Pulsating Conditions
TL;DR: In this paper, the performance and detailed flow characteristics of a high pressure ratio mixed flow turbine have been investigated under steady and pulsating flow conditions, and the results indicated a departure from the quasi-steady analysis commonly used in turbocharger turbine design.
