Flow pulsation
WebApr 13, 2024 · In view of the problem that crystalline particles cause wall vibration at a low temperature, based on two-phase flow model, computational fluid dynamics is used to conduct the numerical simulation of internal flows when the valve openings are 20%, 60% and 100% respectively. The molten salt flow may be changed under strict conditions and … WebThe conjugate rotor generates periodic flow pulsation, which results in vibration and noise of the unit. Therefore, the instantaneous flow pulsation of the pump directly affects the stability of the system operation. As shown in Figure 8, the red curve is the pulsating curve of the theoretical flow rate at the outlet of the rotary lobe pump.
