  • That kind of plooping sound the water makes pouring into the bowl is due in part to a process called cavitation (the making of a cavity), where air bubbles created by changes in pressure in the water oscillate and explode, creating teeny shock waves.

  • For your home, and using electiricy, you might want to look into the highly efficient "cavitation" water heaters and other inexpensive methods that basically come on only when you need hot water, and it is basically a special metal disk that spins in the water very fast with a motor.

  • The experts concluded that these were formed by a phenomenon called "cavitation", which is caused by a restriction in the fuel flow to the pump.

  • "Underwater, the prop whine and the cavitation of hundreds of thousands of air bubbles radiate outward into the ocean. The sound wraps around the foreshores of Newfoundland, refracts off the temperature discontinuity of the Gulf Stream, and dissipates into the crushing black depths beyond the continental shelf. Low frequency vibrations propagate almost forever underwater, and the throb of the Andrea Gail's machinery ust reach just about every life form on the Banks."

  • "A hydrostatic seal provides control of a sealing surface taper as well as the cavitation reduction structure between the sealing surfaces. Control of sealing surfaces taper is provided through one or more relief recesses in the wall. Sounds complex, but it really isn’t."
