We study asymmetric jet and slug formation in collision of two plane flows at a finite distance from stagnation point. Analytic expressions for width and flow direction of jet and slug are given on a solution ellipse. The jetting process is simulated with Euler hydrocode of high order precision and YOUNGS algorithm for tracking interfaces. Predictions are more accurate than results of other analytic models and are in agreement with KS experimental data. With increase of asymmetry between incoming flows, flow direction of slug changes considerably, whereas the direction of jet barely deviates from the direction of symmetric bisector of incoming flows.

A hybrid computational method and the corresponding software for simulating oil well perforator are described.A good agreement has been obtained between computational results and experiments.This research indicates that the software has a higher ratio of effectiveness over cost.
