Cavitation Heating

  • Cavitation Heating Documented

    This video was taken early on during the development of CCES prior to our understanding that cavitation was the only plausible source of the observed heating.

    This test is 5.03 minutes long. We have two thermocouples and the Digital control. We turn the control down to 260 F after preheating the impact chamber to 375F. It is observable as the middle value in the video. The top display represents the temperature reading of a thermocouple inside one of the heaters. The Bottom thermocouple measures the steam resulting steam Temperature. We are going to vary the injection pressure from 10,000 to 20,000 and measure the temperature of the steam.

    In the first view of the gauges you will note that the digital control is set to 260 F and it does not vary during the source of the test.

    The thermocouple inside the heater is 373 F and the Steam is 392 F

    As the video proceeds the heater thermocouple is reads 363 and the steam 404 F

    In the next three at 39 seconds the steam is up to 406 and at 48 seconds it is 407 degrees F.
    at 1 minute and 13 seconds it is 408 degrees F.

    As the video progresses, we turn down the injector pressure and then go back to 20,000 psi.

    At 3 min. 59 seconds we are at 3.80 F
    Then at 4 min. and 25 sec. we are at 381 degrees F and the digital control is still 260 F

    Everything in this test occurs with the heaters turned off. As can be observed all the energy to make steam is generated by the Cavitation. This test has no salt water

    It should be noted that these tests were run on an early prototype within which there is no insulation around the injector. This results in significant heat loss. The new redesigned impact chamber array has special ceramic insulation around the base of the injectors as well as insulation around the bottom of the array to retain as much heat as possible, thus assuring that most all of the heat generated is applied to the formation of steam.
