It's applied to the mixture. I could compute the PLI using the formula but I am not sure on the value of time to use because the simulation is steady state.

However, I have run the same simulation without the multiphase model and those huge spikes are gone:

 

The final values of the UDS do not change between the two simulations though, for example for the avg scalar 0 I get this with the multiphase model:

And this is from the simulation without multiphase model:
