DOI: 10.1063/5.0060406
Abstract: The pressure distribution of the combustion system with a large aspect ratio is uneven, and the process of gas flowing out through the vent holes arranged along the axial direction is inconsistent. Therefore, a multi-vent… read more here.

DOI: 10.1103/physrevlett.125.074501
Abstract: Wall-bounded turbulent flows can take different statistically stationary turbulent states, with different transport properties, even for the very same values of the control parameters. What state the system takes depends on the initial conditions. Here… read more here.
