Biography:

Dr Szymański is a research fellow in turbomachinery aerodynamics in the Propulsion Engineering Centre at Cranfield University. Artur obtained his PhD in Turbomachinery Design and Exploitation from Silesian University of Technology SUT (Gliwice, Poland) in 2017. His research experience combines a wide range of industrial application problems. He brings together industrial needs for robust technical solutions with an academic interest in fine details that define the shape of products.

During his PhD studies, he worked as a Research Assistant in SUT on the INNOLOT project, where he focused on jet engines’ innovative sealing solutions optimisation and testing. Alongside this activity, Artur supported experiments oriented on wet air and steam flow phenomena investigation at transonic conditions, typical for industrial applications. After his PhD, he joined Cranfield (2017), where he met the research group focused on industrial and aerospace compressors aerodynamics as well as combustion chambers at highly off-design conditions, within TURBO-REFLEX project. His part was the development and supervision of CFD works carried out in the team. Recently (2021), he started a new endeavour and works on supersonic intakes aerodynamics.

Artur’s research interests are computational fluid dynamics methods for turbomachinery, multiphase flows for industrial applications and turbomachinery optimisation for the energy transition.

Abstract:

Nowadays energy grid transforms towards renewable energy sources, such as wind and solar. They pose a substantial challenge on grid operators due to their intermittent nature, as the conventional technologies must plug the gap between the demand and generation. This talk focuses on the 3D CFD studies on the effects of highly off-design operations on the flow conditions in gas turbine compressor. The essential contribution is the examination of limits for off-design operations, defined with stall onset and choking.
