Validation of shock-wave/turbulent boundary-layer interaction flows by high-fidelity numerical simulations (2022)
Presentation / Conference
Zheltovodov, A. A., Fang, J., & Yao, Y. (2022, August). Validation of shock-wave/turbulent boundary-layer interaction flows by high-fidelity numerical simulations. Paper presented at The 21st International Conference on the Methods of Aerophysical Research (ICMAR 2022), Russia and online

Shock-wave/turbulent-boundary-layer interactions (SWTBLI) are prevalent phenomena around high-speed vehicles. The resultant strong adverse pressure gradient will induce large flow separation, high wall heat flux, and strong pressure fluctuation, alon...

Transient CFD modelling of air–water two-phase annular flow characteristics in a small horizontal circular pipe (2022)
Journal Article
Yao, J., & Yao, Y. (2022). Transient CFD modelling of air–water two-phase annular flow characteristics in a small horizontal circular pipe. Fluids, 7(6), Article 191. https://doi.org/10.3390/fluids7060191

The liquid film formed around the inner walls of a small horizontal circular pipe often exhibits non-uniform distributions circumferentially, where the film is thinner at the top surface than the bottom one. Even with this known phenomenon, the probl... Read More about Transient CFD modelling of air–water two-phase annular flow characteristics in a small horizontal circular pipe.
