Class
Foam::ConeNozzleInjection
Description
Cone injection
Andrew Heather
committed
User specifies
- time of start of injection
- injector position
- direction (along injection axis)
- parcel flow rate
- inner and outer half-cone angles
Additional
- Parcel diameters obtained by size distribution model
- Parcel velocity is calculated as:
Andrew Heather
committed
- Constant velocity
U = \<specified by user\>
- Pressure driven velocity
U = sqrt(2*(Pinj - Pamb)/rho)
- Flow rate and discharge
