Reaction Inside Nonisothermal Particles

The mathematical description of such a situation would comprise the continuity equations for the fluid and solid reactants encountered in Sec. 4.3 for the unreacted shrinking-core model and a heat balance that assumes pseudo steady state in the shell and an integral averaged temperature in the core up to the frcmL 

Luss and Amundson [19] discussed alternate theoretical models for moving boundary reactions in nonisothermal particles, and concluded that they all gave similar predictions. 

Sohn [20] has developed several analytical solutions to the combined beat and mass balances for the shrinking-core model, using the following assumptions (1) slab geometry, also applicable to other curved geometries for the practical case 

An interpolation formula was also provided, but an estimate is able to be sketched from the above two results, especially for the most important range of 

Further aspects of this problem have also been discussed by Sampath and Hughes
