Abstract
An algorithm for controlling submerged jets has been developed to calculate the geometry of the forming device, which provides the velocity profile and (or) the required characteristics of its linear instability in the initial section of the jet. A class of forming devices is considered, the geometry of which is similar to the geometry of the device created at the Research Institute of Mechanics of the Moscow State University. The control algorithm is based on the gradient descent method to minimize the functional relating the parametrically specified shaper geometry and the selected characteristic of the corresponding initial jet velocity profile formed by it. The operation of the algorithm was tested on the example of a functional describing deviations of the jet velocity profile from the given one
