This source condition sets the values of the number field to recover a specified total volume or mass. It should be used in conjunction with an instantaneous injection model.
This condition requires a uniform size to be specified. All injected parcels will have the same value of this size. The size can be number, surfaceArea, volume or mass. This choice relates to the desired discretisation of the Lagrangian material. Broadly, the uniform size chosen should be that against which the dominant effect of the Lagrangian model scales.
So, if the particles are primarily evaporating droplets of fuel, then the effect of each will be primarily a function of the mass of fuel that evaporates into the system. The uniformSize should therefore be set to mass.
But, if the model is purely dynamic, and the dominant effect is viscous drag, then each particle will exert a force in proportion with a reference area. In this case surfaceArea would be a better choice.
If a distribution of sizes is injected then the choice of uniform size interacts with how the distribution is to be sampled. For that reason, it is important to use a diameter source condition such as distributionDiameter which accounts for this, rather than the general distribution condition.
| Property | Description | Required? | Default |
|---|---|---|---|
uniformSize | The size kept uniform across all parcels | yes | |
volume | The total volume to inject | if mass is not specified | |
mass | The total mass to inject | if volume is not specified |
Example specification:
<LagrangianModelName>
{
type totalNumber;
uniformSize volume; // number, surfaceArea, mass
mass 1 [g];
