HYD Bosch Fuel Properties calculation

Fuel Properties calculation We consider three different cases to compute the Bosch fuel properties:

Case 1:	P > PHvap	there is liquid and free gas
Case 2:	PLvap < P < PHvap	there is some liquid, some vapour, and free air/gas
Case 3:	P < PLvap	there is vapor and All the air/gas is free (no liquid)

The main assumptions are:

• The evolution of the fluid is isentropic.

• The gas used is always air.

• The air is always free (no dissolution of air within the liquid).

• The “air/gas content” does not vary with time or position.

• The volume of the free air/gas/vapor is assumed to vary with pressure in a way determined by a constant polytropic index Γ.
