Direct numerical simulations (DNS) are performed of a cantilevered stator blade to identify the unsteady and turbulent flow structure within compressor tip flows. The simulations were performed with clearances of 1.6 and 3.2 percent of chord. The res

The isentropic exponent is one of the most important properties affecting gas dynamics. Nonetheless, its effect on turbine performance is not well known. This paper discusses a series of experimental and computational studies to determine the effect

This paper investigates the surface boundary layer and wake development of a compressor blade at a range of low Reynolds number from 45000 to 120000. Experiments in a miniature linear compressor cascade facility have been performed with detailed surf

The compressibility factor Z is one of the most common properties that describes a fluid diversion from an ideal gas. Still, its effect on turbine performance is not well known. We determine a set of non-dimensional parameters that fix the gas dynami

Further improvements in aero-engine efficiencies require accurate prediction of flow physics and incurred loss. Currently, the computational requirements for capturing these are not known leading to inconsistent loss predictions even for scale-resolv

The isentropic exponent is known to have a large impact on turbine aerodynamics yet there is little research into how this impacts the development of turbine wakes. This study aims to explore how the aerodynamics of a supersonic turbine cascade are a

The flow dynamics within the multi-stage compressors are complex and not well understood. To study them we employed high-fidelity computational fluid dynamics simulation. In our simulation we mimic the multi-stage environment using an idealised repea

Due to the vast number of potential working fluids incorporated within heat recovery cycles, there is a degree of uncertainty around the aerodynamic design and performance of the required turbomachinery. This paper aims to explore the aerodynamic per

In this paper, we study the effect of rotor-stator axial gap on midspan compressor loss using high-fidelity scale-resolving simulations. For this purpose, we mimic the multi-stage environment using a new numerical method that recycles wake unsteadine
