Physical Simulation of Particle-Laden Gas Flows

The physical simulation and mathematical simulation of heterogeneous flows pursue one and the same objective, that of constructing the theory of multiphase flows. This objective may apparently be achieved by using separately either the experimental or the computational methods of investigation. At the same time, it is apparent that each one of the simulation methods is characterized by a number of inherent advantages and disadvantages. Therefore, the process of construction of the theory will be more effective if the means of physical and mathematical simulation are mutually complementary. Possible ways of such interaction are obvious. For example, measurement results are extensively used to verify the mathematical models being developed. Note the importance of experimental data essential for the formulation of the boundary conditions for the dispersed phase of a heterogeneous flow. In turn, the calculation results are called upon to minimize the required volume of experimental data and to contribute to a more profound interpretation of measurement results.
