When the proposed water-lubricated textured groove thrust bearing is under high speed, the initial cavitation number will increase, so the cavitation effect should be considered when modelling.
The previous research has established that cavitation obviously exists in the textured bearing, including thrust bearing under hydrodynamic lubrication and mechanical seals.
Hara Prakash Mishra as it is known Cavitation occurs when the liquid in a pump turns to a vapor at low pressure. It occurs because there is not enough pressure at the suction end of the pump, or insufficient Net Positive Suction Head available (NPSHa). When cavitation takes place, air bubbles are created at low pressure. Please sleep on the following article i hope it will help you

Cavitation is the consequence of reduced pressure at prevailing temperatures causing a reduction in boiling point.
The hydrodynamic textured grooved thrust bearing action must have resulted in reduced pressure at some sections during operation and thus, the resultant cavitation
Sajid Ahammed thanks for the information. But am unable to correlate cavitation in bearing and pump.
