摘要：
The design of the vortex chamber, which is a cylinder with a partially cut wall was developed. Several such chambers may be contained in the device. One of the structural elements of the device is rotated at a given speed. An intensity of the arisen vortex depends on the relative speed of a couple chamber-agitator, and the opening angle of the vortex chamber. Investigation of the structure of vortex flows is to determine profiles of peripheral and axial velocities in the vortex chambers. Studies have revealed the presence of self-oscillations in the investigated flows. Rational values of the opening angle of the vortex chamber that ensure maximum peripheral speed should be selected from a range of 60-100A degrees.
