In this approach, the finite volume methods discussed in the previous chapter can be applied to simulate the continuous fluid (in a Eulerian framework). Various algorithms for treating pressure-velocity coupling, and the discussion on other numerical issues like discretization schemes are applicable. The usual interpolation practices (discussed in the previous chapter) can be used. When solving equations of motion for a continuous fluid in the presence of the dispersed phase, the major differences will be (1) consideration of phase volume fraction in calculation of convective and diffusive terms, and (2) calculation of additional source terms due to the presence of dispersed phase particles. For the calculation of phase volume fraction and additional source terms due to dispersed phase particles, it is necessary to calculate trajectories of the dispersed phase particles, in addition to solving the equations of motion of the continuous phase.

Diffusion approach The diffusion approach being the simplest algorithm for treating reactive products evolves the interparticle separation by diffusion independently of other such distances. Thus, if at time t the interparticle separation is r, then at t the new interparticle separation is r = r - - N3(0,l), with N3(0,l) being a three dimensional normally distributed random number with mean zero and variance 2D t, with D being the mutual diffusion coefficient. 

Chapter 6 presents two new algorithms for treating reactive products in the IRT framework. These have been tested for two chemical systems (i) photodissociation of H2O2 where the OH are scavengeable (ii) water photolysis which produces H+, OH and e. In the latter case a careM handling of three body correlations is required.
