- Droplet impact on superheated smooth solids has attracted enormous attention since Leidenfrost reported the eponymous phenomenon over 250 years ago.
- Along with the anti-cavitation performance, the high speed and the high power density, are the main trends in the development of centrifugal pumps.
- The observation of ultrasound generated cavitation bubbles deep in tissue is very difficult.
- Solution gas drive in reservoirs containing heavy and viscous oil is not well understood.
- Most materials tend to cavitate during deformation and cavitation damage is responsible for the premature failure of materials.
- The qualitative and quantitative effects of proppant on the near-front region of a hydraulic fracture are investigated by solving the problem of a semi-infinite fracture driven by a slurry of Newtonian fluid with proppant.
- Hydrostaticity under high pressure of several materials from solid, fluid to gas, which are widely used as pressure media in modern high-pressure experiments, is investigated in diamond anvil cells.
- Significance Cavitation, the formation of vapor-filled bubbles in a liquid at low pressures, is a powerful phenomenon with important consequences in nature and technology.
- The wall pressure loading due to the underwater spark-generated bubble, having served as an efficient technique to study the underwater explosion, has drawn much attention.
- Cavitation is of significant practical interest due to its unsteady features which could induce destructive effects such as drastic drop in efficiency, noise, vibration, and corrosion for propulsion systems, rudders and other hydraulic machinery.
- An increasingly notable component of the space environment pertains to the impact of meteoroids and orbital debris on spacecraft and the resulting mechanical and electrical damages.
