Влияние надбандажной протечки на аэродинамику осерадиального диффузора выхлопного патрубка ЦНД паровой турбины при изменении противодавления

Abstract

For axially symmetrical model of diffuser, which characteristic for the exhaust manifold of the LPT power steam turbines, at the change of pressure on the diffuser exhaust are resulted. It is shown that on the certain modes which are related to the change of the backpressure, at supersonic velocity in the peripheral region of diffuser the unsteady processes are initiated.
