On the basis of the discrete vortexes method we developed mathematical model, computational algorithm and computer program for calculation of air vortex flows in leakiness of aspiration chamber equipped with thin glare shields randomly located in space. Regularities of changes of detached flow characteristics when shield is set in the entrance of the leakiness were defined. We compare got specified rates with experimental data and computations made with other methods. The question of reducing of energy-output ratio of aspiration systems by using the effect of jet separation is discussed.
