Particles are injected immediately after the backward-facing step. The Stochastic Turbulence Model is used to simulate particle dispersion due to turbulence. wall ///////////////////////////////////////////////////// ----------------------------------------------------- Pressure Inlet -------> ---------> fixed at zero /________________ | ////////////////| Exit | wall /| Recirculation | /| <---- -----> | /|____________________________________ | ////////////////////////////////////// | wall \ ENDDIS -------------------------------------- 30 * X Y U V DIA RHO MASSFLO 0.0E+00 9.0E-02 11.5 -8.45E-00 1.E-05 100. 5.08E-05 0.0E+00 7.0E-02 11.5 -8.45E-00 1.E-05 100. 5.08E-05 0.0E+00 5.0E-02 4.57 -3.79E-01 1.E-05 100. 1.36E-04 2.4E-01 0.1E-02 1.80 -5.57E-01 1.E-05 100. 1.99E-04 2.0E-01 1.0E-02 8.54 -3.07E-01 1.E-05 100. 1.14E-04 --------------------------------------- ************************************************************ Group 1.
