Based on the system of equations of two phase compressible viscous flow, we performed a two dimensional numerical simulation of momentum transfer by a shock wave propagating from a gas to a con tinuous aqueous medium or an aqueous medium with air bubbles. When a shock wave impinges on a contin uous aqueous medium, the incompressible liquid is set in motion by gas overpressure after the reflection of the shock wave from the gas-liquid interface; however, when a shock wave impinges on a bubbly aqueous medium, the compressible liquid is set in motion due to the penetration of a shock wave into it. Parametric calculations have shown that momentum transfer from a shock wave to a bubbly fluid can be accompanied by dynamic effects, which ensure that the momentum transferred to the bubbly liquid for some time by far exceeds the momentum transferred to a continuous liquid, all other things being equal. These dynamic effects can be used to develop energy efficient hydrojet propulsion units.

Non-intrusive, imaging-based method for shock wave characterization in bubbly gas–liquid fluids

2023

View full text Add to dashboard Cite

A novel experimental imaging-based method is presented for the non-intrusive determination of shock wave characteristics (i.e. shock wave speed and magnitude, and shock-induced liquid velocity) in a bubbly flow solely from gas bubble velocities. Shock wave speeds are estimated by the relative motion between gas bubbles at two locations by splitting the camera field-of-view using a mirror construction, increasing the dynamic spatial range of the measurement system. Although gas bubbles have in general poor tracing properties of the local fluid velocity, capturing the relative dynamics provides accurate estimates for the shock wave properties. This proposed imaging-based method does not require pressure transducers, the addition of tracer particles, or volumetric reconstruction of the gas bubbles. The shock wave magnitude and shock-induced liquid velocity are computed with a hydrodynamic model, which only requires non-intrusively measured variables as input. Two reference measurements, based on pressure transducers and the liquid velocity field by particle image velocimetry, show that the proposed method provides reliable estimates for the shock wave front speed and the shock-induced liquid velocity within the experimental range of 70 $$< U_\textrm{s}<$$ < U s < 400 m/s.
