Summary

When using a passive scalar, what additional computational time can be expected?

Details

Each passive scalar requires an additional transport equation to be solved. 
In the case of a single phase simulation with the k-Epsilon turbulence model, the increase in computational time is about 8% per passive scalar. 
In the case of an Eulerian two-phase simulation with the k-Epsilon turbulence model, the increase in computation time is around 3.5% per passive scalar.
