Heat Transfer in Dispersions


The book presents methods developed for engineering solutions of the multiple problems in heat and mass transfer and electrical discharge in heterogeneous and multiphase media of different structure and different conditions. The transport phenomena in chemical phase transitions are presented in a manner applicable to the chemical, mining, metallurgical, energy generation, and other widely used technological fields.
