Abstract: The flow structures and heat transfer within rotating cavities of aero-engine axial compressors influence the thermal expansion of the rotor disks, and consequently the blade-tip clearances. To investigate the flow field ...

Abstract: The buoyancy-induced flow structure and heat transfer in rotating cavities is a well-known conjugate problem. The disk temperatures affect the flow and vice versa. This creates a challenging environment to study as it is ...

Abstract: Recently, physics-informed neural networks (PINNs) have displayed great potential in delivering swift and accurate solutions for inverse problems. Here, a PINN was used to solve the inverse heat conduction problem in the ...

Abstract: The buoyancy-induced flow and heat transfer inside the compressor rotors of gas-turbine engines affects the stresses and radial growth of the compressor disks, and it also causes a temperature rise in the axial throughflow ...
