The paper presents a method for expanding the working range of separation elements, where the separation is conducted through the use of inertia particles. The presented dynamic separation elements work as the automatic control system (the regulating action is the elastic energy; the regulation object is the hydraulic resistance). It was taken the first step to the engineering method development for their calculation using analytical dependences of the finite element method. The critical velocity of the gas-liquid flow was determined, that causes a divergence phenomenon of dynamic separation device elements and expressions for generalized forces for the system “gas-liquid flow is a dynamic deflection element.” Two-knot finite elements with two degrees of freedom (transverse displacement and angle of the cross-section rotation) were used for dynamic deflection elements. The given number of degrees of freedom of the mechanical system “gas-liquid flow is a dynamic deflection element” due to the consideration of the transverse deformations of the plate allows simplifying the mathematical model. It was suggested to use aerohydroplastic phenomena of dynamic non-stability of dynamic deflection elements of separating devices, analogous to the method of applying acoustic oscillations to a heterogeneous stream, for the coagulation of dispersed particles in the flow.
