News / WEBINAR: A Detailed Loss Analysis Methodology for Centrifugal Compressors by Entropy Production Rate

What awaits you?

In order to  meet the ever-growing requirements on high efficiency and wide operational range for centrifugal compressors for application such as chiller, fuel cell compressor, turbochargers and industrial applications, an effective detailed loss analysis is required by the designer. In this webinar an evaluation methodology for computational fluid dynamics simulations have been developed to quantify the loss generation based on entropy production rate in the flow field. A breakdown of losses caused by different mechanisms (such as skin friction, secondary flow, tip clearance vortex and shock waves) is achieved by separating the flow field into different zones. Each zone is defined by the flow physics rather than by geometrical locations or empirical correlations, which makes the method a more general approach and applicable to different machine types.

The method has been applied to both subsonic and transonic centrifugal compressors, where internal flow is complex due to the Coriolis acceleration and the curvature effect. An evaluation of loss decomposition is obtained at various operational conditions. The impact of design modification is also assessed by applying the same analysis to an optimized design.

When?

 Join us on the 30th of June, at 9 AM and / or 4 PM BST.

Who is it for?

The event addresses all engineers, developers or researchers dealing with turbomachinery design.
The method is interesting for small and medium companies as well as enterprises.

Meet the Speakers

Prof. Mehrdad Zangeneh and Dr. Luying Zhang, Senior Turbomachinery Design Engineer at Advanced Design Technology, will be presenting the webinar. 

Mehrdad Zangeneh is founder and managing director of Advanced Design Technology and Professor of Thermofluids at University College London. His research interests cover development of computational design methods based on 3D Inverse Design and automatic optimization to a variety of turbomachinery applications (such as pumps, turbines, compressors and pumps). More recently he has focused on the development of multi-disciplinary optimization methods that aim to improve both aerodynamic and structural performance of turbomachinery. He has published more than 120 papers in journals and refereed conferences and has been granted 7 international patents.

Luying Zhang got her Bachelor and Master degree of Engineering from School of Aerospace, Tsinghua University. She received her PhD from Engineering Science Department of Oxford University in 2013. She then worked in Steam Turbine Retrofit of Alstom Power Ltd (Rugby, UK) as an aerodynamicist / thermodynamicist. Furthermore, she also worked in United Technologies Research Center (Shanghai, China) as a senior research engineer. During this time, she specialized in research and development of centrifugal compressor for chiller applications. She was also responsible for developing modelling capability and advanced concepts for two phase flow heat exchangers. Since joining Advanced Design Technology, Ltd. she has been working as a senior turbomachinery design engineer. Her role is heavily involved in the design and performance evaluation for centrifugal compressors and pumps. She is also working on technical support for customers and software development.
