Eddy dissipation model
 
Hi everybody!

I can't understand the following description from the help: In the Eddy Dissipation model, the rate of progress of elementary reaction k is determined by the smaller of the two following expressions:

Reactants limiter: Rk=A*EPSILON/k*([I]/niukI') , where [I] is the molar concentration of component I and I only includes the reactants components.

Products limiter: Rk= A*B*EPSILON/k*(sump[I]Wi/sump(niukI''WI)) where P loops over all product components in the elementary reaction k. The product limiter may be disabled by setting the model coefficient B to a negative value. For multi-step reaction schemes it is turned off by default, but may be turned on by explicitly setting the model coefficient B to a positive value (although this is not recommended).

Can anyone help? ioana

It is all right what you are saying, but what is you're question?
