Beitrag zur Abhängigkeit der Kavitationsintensität von der Wassertemperatur bei Strömungskavitation in Brauchwässern

Abstract: Kavitation in strömendem Wasser setzt sich zusammen aus zwei Schadenskomponenten: mechanische und chemische Schädigung. Die mechanische Schädigung nimmt mit steigender Wassertemperatur ab, die korrosive Wirkung nimmt oberhalb 35° C beträchtlich zu. Da indessen bei Kunststoffen nicht von einer elektrochemischen Korrosion gesprochen werden kann, wird diese Komponente hier vernachlässigbar, d. h. daß die Kavitation von Kunststoffen mit steigender Temperatur abnimmt. Bei höheren Temperaturen spielt dann auch die b… Show more

“…The citations in this section deal with flow cavitation in water, which in contrast to oil contains only marginal amounts of dissolved gas, and consequently, the following citations are works pertaining to vaporous cavitation in general. In his dissertation, Borbe [2] investigated flow cavitation in wastewater and concluded that vapor cavitation is the mechanism that results in material cavitation or erosion. Mottyll [3] simulated cavitation by means of a density-based solver and assumed that the aggressive types of cavitation are related to bubbles collapsing near the surface of solid walls.…”
