Influence of the shock wave-turbulence interaction on the swirl distortion in hypersonic inlet
Zhenlong Wu, Yiqing Li, Limei Lu, Xinyi Xu and Ranhui Liang
https://doi.org/10.1186/s42774-024-00183-3
Quick Overview
This study employs Large Eddy Simulation to analyze flow characteristics in a hypersonic inlet under Mach 6, focusing on how shock wave-turbulence interactions influence swirl distortion at the inlet exit. The findings reveal that variations in incoming flow conditions significantly affect exit swirl distortion by altering the behavior of incident and reflected shock waves, while also impacting the wall heat transfer coefficient. The research offers insights for understanding and optimizing hypersonic inlet performance across different flight conditions.

Comparative study on predicting turbulent kinetic energy budget using high-order upwind scheme and non-dissipative central scheme
Dandi Wang, Yiming Du, Yao Jin, Jinsheng Cai and Fei Liao
https://doi.org/10.1186/s42774-024-00187-z
Quick Overview
This study compares the predictive capabilities of a high-order upwind scheme and a second-order non-dissipative central scheme for turbulent kinetic energy (TKE) budget in low Mach number flows. The high-order upwind scheme, despite its dissipation limitations at high wave numbers, outperforms the central scheme, particularly on coarse grids, and is further applied to analyze TKE in turbulent flow over a multi-element airfoil, revealing distinct patterns in production, dissipation, advection, and diffusion terms.

https://doi.org/10.1186/s42774-024-00185-1
Quick Overview
This study numerically simulated wind flow around the Milad Tower using computational fluid dynamics (CFD) models, specifically the Reynolds Averaged Navier–Stokes (RANS) and Delayed Detached Eddy Simulation (DDES) models. The simulations showed good agreement with wind tunnel data regarding pressure distributions, and the DDES model outperformed others in predicting aerodynamic coefficients and velocity fluctuations around the tower.

A novel wall interference correction method for airfoil
Binbin Wei, Yongwei Gao, Ruiyang Qiao and Shuling Hu
https://doi.org/10.1186/s42774-024-00193-1
Quick Overview
This study presents a novel method, the non-uniform wall pressure signature method (NUWPSM), for correcting wind tunnel experimental results affected by tunnel wall interference in airfoils. The NUWPSM, along with an improved version of the wall pressure signature method (WPSM), effectively addresses velocity disparities and systematic errors, demonstrating superior capabilities in simulating axial induced velocity distribution and achieving precise corrections across a wide angle of attack range.
