In this webinar, you will learn how to approach the design of high performance hydrogen compressor and pump and discover how TURBOdesign Suite combined with Ansys Workbench can be used to design these turbomachinery components.
Cummins Turbo Technologies is a leading designer and manufacturer of turbochargers for diesel and gas-derivative engines above 2.3 litres. They have developed advanced turbocharging technologies to enable engine manufacturers to meet strict emissions criteria and engine performance requirements.
This webinar present a rapid and efficient design and optimization process for axial contra-rotating fans. The speakers - Prof. Mehrdad Zangeneh, Saurabh Gupta and Tobis Sieger - present application of TURBOdesign tools for the preliminary multi-blade row design of the axial fan where the rpm and pressure rise repartition of the different stages are varied. The results of the preliminary design work are shown to be in excellent agreement with 3D CFD validating the overall design process and solution.
The application of the method is explored using a transonic test case, NASA rotor 67. From an understanding of the dynamics of the flow in the fan in relation to its pressure loading distributions,simple guidelines can be developed for the inverse method in
order to weaken the shock formation.
An inverse design methodology is presented for the design of turbomachinery blades using a cell-vertex finite volume time-marching algorithm in transonic viscous flow. In this method the blade shape is designed subject to a specified distribution of pressure loading (the difference in pressure across the blade) and thickness distribution.
The development and application of a three-dimensional inverse design for turbomachinery blades is described in this paper. The method solves for the blade geometry based on the prescribed mass-averaged swirl velocity across the blade span and a fixed tangential blade thickness.
The design of transonic multistage axial turbines and compressors of the type used in aero-engines and industrial gas turbines poses difficult and challenging problems to turbomachinery designers. In aero-engines, there is an increasing trend to reduce engine weight, which is only possible by increasing stage loading coefficient and reducing the axial spacing between the stages.
In the present paper, the redesign of a transonic rotor was performed by means of a three-dimensional viscous inverse design method. The inverse approach used in this work is one where the pressure loading, blade thickness distribution and stacking axis are specified and the camber surface is calculated accordingly
This paper compares the performance of a conventional turbocharged engine model with a two-stage boost engine model equipped with a decoupled electric turbocharger. A carefully designed control strategy is designed for the electric turbocharger for a variety of engine speed/load conditions.
This paper reports a recent study of using inverse design method for the redesign of a centrifugal compressor stage used in an electric supercharger, including the impeller blade and volute.
Automatic optimization techniques have been used in recent years for the aerodynamic and mechanical design of turbomachinery components. In this paper, an optimization strategy is presented, which enables the three-dimensional multipoint, multi objective aerodynamic optimization of turbomachinery blades in a time frame compatible with industrial standards.
