Abstract

The probabilistic restitution model was adopted by fitting probability functions with Gauss-Hermite method for the integral inlet separator particle trajectory simulation compared with deterministic restitution model and elastic collision model. Result shows that the above three bounce models perform well in AC coarse sand separation prediction. For C-spec sand, results based on elastic collision model deviate from test data seriously, and the deterministic restitution model over predicts its separation efficiency, especially for the swirling inlet particle separator, while the probabilistic restitution model achieves an intermediate value which shows a good agreement with test data.
