NUMERICAL STUDY OF A FREE JET MULTINOZZLE SOURCE

In experiments with molecular beams, negative, positive and neutral cl usters are usually generated by an influence on the continuous region of the supersonic flow. Such an influence can disrupt the supersonic m ode of the flow. A model of a multinozzle source suggested earlier see ms prospective and is the object of mathematical simulation. Flow from several orifices is difficult to investigate, so the flow from severa l slits of infinite length in suitable configuration was studied. The main result of the calculations is that the close localization of sour ces does not obscure the supersonic flow, and the disturbances introdu ced into the flow by arising shock wave structures are weak.
