Název v původním jazyce

Analysis of aerodynamic forces mathematical models acting on tube bundle

Popis výsledku v původním jazyce

Tube heat exchangers are inseparable components of almost every energetic machinery, where one fluid flows through tubes and the other fluid flows around the tubes. There exists heat transfer between these two fluids. Apart from the problem of heat tr ansfer, the problem of fluidoelastic 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 flow. Under the c ertain, so-called critical velocity, vibration amplitudes can suddenly increase. The loss of stability occurs. It is necessary to avoid such regimes of operations, when the damage of heat exchange could be arrive as consequence of flow-induced vibrati on.
