Losev model

Figure 2- 1. Experimental and theoretieal values of the non-equilibrium dissoeiation factor Z as function of translational gas temperature in (a) molecular oxygen, (b) molecular nitrogen, and (c) molecular iodine (1) Macheret-Fridman model, (2) Kuznetsov model, and (3) Losev model.

Losev Model (Losev Generalov, 1961). According to this model, the dissociation rate coefficient can be found using the conventional Arrhenius formula for equilibrium reactions with vibrational temperature Ty and effective value Defr of dissociation energy. To find Deff, the actual dissociation energy D should be decreased by the value of translational temperature taken with efficiency P ... 

The coefficient is a fitting parameter of the Losev model, and for most estimations it can be taken as 1.0-1.5. The Macheret-Fridman model permits the Losev semi-empirical...
