In this work, combustion instability of the solid-fueled ramjet (involving diffusion-dominant
combustion process) is investigated using a numerical model. Effects of inlet thermodynamic …

Supersonic gaseous jets with large ambient pressure are typically found in deep-water
propulsion systems. The interactions between gas and water are turbulent, and the plume …

In practice, gas usually escapes from non-circular orifices due to machining accuracy,
plugging, and other reasons, especially gas leakage in the natural environment. Compared …

Propagation of detonation waves crossing the gas–liquid interface is a basic phenomenon
worth studying for underwater detonation engines. In this work, the pressure evolution of …

This study develops a three-dimensional imaging system to obtain comprehensive
information on asymmetric bubbles formed in five nozzles with exits of the same cross …

Numerical simulation of the underwater outflow of a supersonic overexpanded air jet is
considered. The calculations are carried out in an unsteady three-dimensional formulation …

This paper provides a first insight into the transition from bubbling to jetting of submerged
jets generated by the ejection of gas-liquid mixing flows through a minichannel into water …

Gas curtain launch is an innovative method for underwater gun firing that enhances
efficiency by creating a gas curtain. This gas curtain interacts with post-projectile gas and the …

The temporal mode stability of incompressible submerged axisymmetric gas jets is
comprehensively investigated by linear stability analysis. The basic velocity profile is …

Underwater supersonic gas jet flows are sophisticated physical phenomena that widely exist
in underwater propulsion, such as underwater rocket, high‐speed torpedo, and water …
