A New Method for Rapid Optimization Design of a Subsonic Tandem Blade
Applied Sciences, 2020 Tandem blade technology has been developed for years due to its capacity to bear higher aerodynamics than conventional configurations. Even so, there is still the tough problem of how to design tandem blades effectively and further improve blade ...

Deterministic Stress Modeling for Multistage Compressor Flowfields [PDF]
, 2013 Unsteadiness is one of the main characteristics in turbomachinery flows. Local unsteady changes in static pressure must exist within a turbomachine in order for that machine to exchange energy with the fluid.

Accurate 2-D Modelling of Transonic Compressor Cascade Aerodynamics
Aerospace, 2019 Modern aeronautic fans are characterised by a transonic flow regime near the blade tip. Transonic cascades enable higher pressure ratios by a complex system of shockwaves arising across the blade passage, which has to be correctly reproduced in order to ...

Periodic transonic flow and control [PDF]
, 2008 The current understanding of periodic transonic flow is reviewed briefly. The effects of boundary-layer transition, non-adiabatic wall conditions and modifications to the aerofoil surface geometry at the shock interactions on periodic transonic flow are ...

Numerical Simulation of Transonic Compressors with Different Turbulence Models
Aerospace, 2023 One of the most commonly used techniques in aerospace engineering is the RANS (Reynolds average Navier–Stokes) approach for calculating the transonic compressor flow field, where the accuracy of the computation is significantly affected by the turbulence

Test Facility for High-Speed Probe Calibration [PDF]
EPJ Web of Conferences, 2019 A new test facility was built up as a part of a closed-loop transonic wind tunnel in VZLU´s High-speed Aerodynamics Department. The wind tunnel is driven by a twelve stage radial compressor and Mach and Reynolds numbers can be changed by the compressor ...

Stochastic axial compressor variable geometry schedule optimisation [PDF]
, 2011 The design of axial compressors is dictated by the maximisation of flow efficiency at on design conditions whereas at part speed the requirement for operation stability prevails.

International Journal of Rotating Machinery, 2004 Current research concerned with the aerodynamic instability of compressors aims at an extension of the operating range of the compressor towards decreased massflow. In practice, a safety margin is maintained between operating point and stability limit to
