WebThe low-pressure characteristic of the TLV core results in cavitation in the original model. The location of the cavitation matches the TLV in Fig. 6 and the low-pressure region in Fig. 12 . However, the volume of the cavitation is smaller than that of the TLV because the pressure in the vortex core gradually increases and becomes higher than the water …
