IMPLEMENTATION AND EXPERIMENTAL VALIDATION OF A STOCHASTICAL INTERPARTICLE COLLISION MODEL
Sprache des Vortragstitels:
This work deals with simulation and measurement of a particle-laden gas flow in a duct. An interparticle collision-model for particles tracked in a Lagrangian frame, developed by M. Sommerfeld (1996), is discussed before an alternative model extension is presented. This model is applied to an experimental test case, which is the flow through a rectangular tube with a cross-section reduction.
The measurement techniques are discussed and finally the measurement results are compared with the data of the corresponding CFD simulation.
The comparison clearly shows that without adding the collision sub-model the simulation with the standard Lagrangian model yields unreasonable results. With the stochastical collision sub-model the Lagrangian model is able to describe the flow situation if the mass load is not too high.
