For example, the cavitation number can be expressed as:
A more complex cavitation number equation was recently proposed by Sou et al.
s]--Coefficient in Sou's cavitation number equation
infinity]] [square root of 1 + [sigma]] may be obtained for the flow on the cavity surface by using the Bernoulli equation, in which [sigma] is the cavitation number and is defined as follows:
According to the abovementioned boundary conditions, the cavitation number being known, [phi], on the cavity and reentrant jet is calculated from (9) and (11), and [partial derivative][phi]/[partial derivative]n on the body and reentrant jet is calculated from (6) and (10).
Using Gaussian elimination to solve this system of linear equations, the strengths of the dipoles and sources and the cavitation number are calculated.
It is composed of the cavitation number ([sigma]), pressure coefficient gradient ([C.
The cavitating flow regimes related to the cavitation number, [sigma] = 0,59, and [sigma] = 0,64 defined the value of the saturation pressure [P.
The cavitating flow regimes related to the cavitation number, [sigma] = 2,4 and [sigma] = 2,44 defined the value of the saturation pressure [P.
The major pressure pulsations frequency increases with cavitation number.
When the cavitation number
becomes zero, cavitation will begin to occur.
In view of the desired and anticipated range of cavitation numbers
and with the selected range of test section flow velocities, the range of test section static pressure was chosen to be 0.
