dcterms:description
Trubkové svazky jsou nedílnou součástí velkého počtu energetických zařízení, kde jedna tekutina proudí uvnitř trubek a druhá proudí vně trubek. Mezi oběma tekutinami dochází k přenosu tepla. Kromě problému přenosu tepla je taká důležitá interakce tekutinou a obtékanou strukturou. Zejména tekutina proudící vně trubek může být nebezpečná, protože způsobuje jejich vibrace. Intenzita těchto vibrací závisí na rychlosti proudu tekutiny. Za určité, tzv. kritické rychlosti mají amplitudy vibrací náhodný charakter. Předmětem tohoto článku je určení pravděpodobnosti překročení určité hraniční hodnoty amplitudy vibrací. Je třeba zvolit takový režim provozu, při kterém Tube heat exchangers are inseparable components of a great number of energetic machinery, where one fluid flows through tubes and the other fluid flows around the tubes. Heat transfer occurs between these two fluids. Apart from the problem of heat transfer, the problem of fluid-structure interaction is very important too. Mainly the fluid flowing around the tubes may be very dangerous, because it causes vibrations of these tubes. Intensity of vibration depends on the velocity of the flow. Under the certain, so-called critical velocity, vibration amplitudes can have random pattern. The objective of this article is to determine the probability of up crossing of some fixed level. It is necessary to avoid such regimes of operations, in which the damage of a heat exchanger as a consequence of flow-induced vibration could not be caused.
