How to define a leak
You can define a leak by clicking on the scenario menu. In this case, you will need to enter all the input required manually.button in the section in the
Alternatively, you can right-click in the white area of the Leak wizard to define a leak. If you choose to use the Leak wizard, you can either enter the input manually or use the Jet utility to calculate a steady-state or time-dependent leak based on the inventory characteristics and the leak size.
You can define up to 50 leaks in a given scenario; the different types of leaks are briefly described below.
A Diffuse leak is a no-momentum release of gas into the grid cell chosen.
A Jet leak specifies a low or high momentum release. A Jet leak can be either a point or area leak.
Same as Jet but with modelled entrainment. The entrainment functionality is used to define the evolved leak conditions and positions.
An Air leak will release air (or, in general, the mixture defined by the equivalence ratio ER9) instead of fuel (or, the mixture defined by the equivalence ratio ER0); otherwise it is similar to a Jet leak.
A Suction leak is a negative point source, that is, gas/air will be removed at the leak location.
A Fan leak does not add or remove mass, but assigns a fixed momentum to the fluid in the concerned control volume.
A leak of Inert type releases the specified inert gas rather than fuel (only in the Inert simulation type).
