A difficult problem that faces the design of any combustion equipment is the fact that the flows are turbulent and often complex and defy a complete analytical description. Mixing processes are very important in any fast reaction and often they are the dominant factor. The investigation encompasses research to evaluate the possible effect of the stochastic and non-uniform nature of the transport processes on non isothermal nonlinear reactions. New approaches to the evaluation of the magnitude of these interactions are made, and phenomenological models for turbulent flows are proposed, and related to real flows by tracer experiments. The use of tracer experiments in the design and study by turbulent combustion reactors is discussed and a theoretical framework for the evaluation of tracer experiments in fluctuating quasi-steady flow systems is presented. The advantages of using reacting tracers in reactor modeling is discussed. Design criteria for stirred combustors are given and the effects of imperfect mixing and fluctuating inputs on such reactors is described. Design and modeling of fluidized bed reactors is also treated.
