Hy,
I am designing a fuel pump for an aircraft engine application. The pump have to function correctly with low pressure inlet condition (Pinlet-PTVP < 0.2bar) and a V/L ( Vapor volume/ liquid volume) of 0.45.
An inducer is used to reduce the V/L.
I have got 2 questions concerning this application:
1- As the fluid density decrease with the V/L, the NPSHA increase...But what is the influence of the V/L on the NPSHR? How can I determinate it?
2- I assume that radial impeller can work with a low V/L condition.
Which V/L is admissible at the impeller inlet?
Thanks for answers!
