Intraparticle diffusion and char combustion
Chemical Engineering Science, 1986 Abstract A diffusion and reaction model describing the combustion of porous char particles is developed and used to study the effects of intraparticle diffusional limitations on their pseudo-steady state and dynamic behaviour. The model allows for intraparticle temperature gradients and shrinkage of the reacting particles. Extensive computations over

THE MODIFIED MODEL OF DIFFUSION FLOW OF MULTICOMPONENT COMBUSTIBLE GAS
Известия высших учебных заведений: Нефть и газ, 2015 The model of gas diffusion combustion developed by Zeldovich Ya.B., despite of the fairly satisfactory agree-ment of the obtained data with the experiment shows a non-universality and a large volume of the algorithm for de-termining the concentrations of
