Detailed Description

template<class CloudType>
class Foam::ConeNozzleInjection< CloudType >

Cone injection.

User specifies:

time of start of injection
injector position
direction (along injection axis)
parcel flow rate
inner and outer half-cone angles

Properties:

Parcel diameters obtained by size distribution model.

Parcel velocity is calculated as:

Constant velocity:
```
      U = \<specified by user\>
```
Pressure driven velocity:
```
      U = sqrt(2*(Pinj - Pamb)/rho)
```
Flow rate and discharge:
```
      U = V_dot/(A*Cd)
```
