recommendations! Published in 2017 at "Journal of Central South University"

DOI: 10.1007/s11771-017-3550-5

Abstract: Using three-dimensional, unsteady N-S equations and k-ε turbulence model, the effect of ambient wind on the pressure wave generated by a high-speed train entering a tunnel was studied via numerical simulation. Pressure changes of the… read more here.

DOI: 10.1017/jfm.2019.1047

Abstract: We investigate the stability of katabatic slope flows over an infinitely wide and uniformly cooled planar surface subject to a downslope uniform ambient wind aloft. We adopt an extension of Prandtl’s original model for slope… read more here.

DOI: 10.1063/5.0277942

Abstract: Unpowered ventilation cap, natural ventilation holds promise for effectively exhausting smoke during tunnel fires. However, the impact of pulsating ambient wind on tunnel fire smoke in unpowered ventilation cap natural ventilation systems remains unclear. In… read more here.

DOI: 10.1080/00102202.2018.1527325

Abstract: ABSTRACT In scenarios of compartment fire, natural smoke exhaust often confronts the challenge of environmental wind. In this work, a series of numerical simulations were conducted to study the influences of ambient wind speed, location… read more here.
