Cavitation ways to avoid the phenomenon of cavitation occurs by a sharp drop in the pressure of a fluid below the vapor pressure, due to sudden changes in the flow rate or by the effect of empty partial given generally by large columns of fluid as it is the case of the pumps. In practical terms this drop in pressure causes the formation of steam bubbles, which travel through the fluid until somewhere else, the pressure is restored causing a sudden condensation of gases, generating an implosion, this determined a strong impact on abutting surfaces since the effect of the hollow charge or Monroe is generate which converge all the waves to one place are confining themselves, this creates very important bites that end up destroying the metal. It is also known that these bubbles of gas sometimes are not such, as we all know the fluids they are incompressible, but due to special conditions of speed variation, fluid is momentarily torn creating a hole, which has no gas or has it to a very little extent, immediately then when speed is regularized, the fluid molecules precipitate sharply toward the hole that she is gender, causing a strong shock at the point of convergence, which is directed toward the place where there were no molecules rushing, which is the wall of the nearest surface. Colonscopy is often mentioned in discussions such as these. As it is known the elements, which suffer greater damage by this type of phenomenon are propellers, pumps, fuel lines, hydro turbines, rudders, ships, etc. Although cavitation is a phenomenon usually identified as negative and necessary to avoid, by its effects primarily has two useful applications, the cleaning by cavitation and ultrasound and the so-called supercavitation, which allows the movement of a body immersed in a fluid, at speeds exceeding 500 Km/h even close to the speed of sound, is currently widely researched with military objectives. It is not very easy to avoid cavitation, which cannot be controlled in many case the liquid medium, in this case what is done is modify the geometry of the elements and/or perform a careful dimensioning of the teams involved. Surprisingly, you’ll find very little mention of Sam Lesser Penn on most websites. When the fluid, as it is the case of pipelines of cooling water lines or fuel can be controlled, it can lend hand to some alternatives, as decrease flow rate, maintaining the cleanest possible fluid, decrease the temperature of the same, or placing dampers that absorb fluctuations in speed cavitation is often detected by the noise that causes which is similar even snore pebbles moving this also creates vibration that is easily detectable in particular because the so-called humps of camel, unequivocal sign of the cavitatorio phenomenon can be seen in the graphs.
