On the relevance of practical application of numerical-theoretical models of oxidation of a carbon material in gas flows

The relevance of the application in practice of two different approaches to the calculation of the rate of carbon heterogeneous oxidation has been analyzed. One of the methods is based on the assumption that the oxidation rate is proportional to the oxidant partial pressure at the wall, while the other presumes the oxidation rate dependence on the velocity of oxidant particles bombarding the wall. The conclusion is made on the relevance of the first approach practical application and the infeasibility of the use of the second one.
