Abstract: The influence of unvented hood on the initial compression wave generated by a highspeed train entering a tunnel is investigated using computational fluid dynamics. Comparisons with experimental data are first carried out ...

Abstract: The micropressure wave radiated from a tunnel exit is one of the environmental problems which can be investigated from the temporal pressure gradient of the compression wave. The effects of inclined portals on the initial ...

Abstract: Cavitation inception in tip leakage flows remains a challenging topic in the engineering field, as the effect of tip gap width on inception is unclear. The present study is devoted to an analysis of the effect of gap width ...

Abstract: Monochromatic wave scattering on a submerged horizontal plate over variable topographies is studied analytically based on the modified matched eigenfunction expansion method. Under the assumption of the shallow flow over ...

Abstract: Experimental results of the void fraction, statistical chord length distribution (CLD), and bubble size distribution (BSD) inside and downstream of hydrodynamic cavities are presented at the laboratory scale. Various ...
