We developed an approach for the reduction of systems of nonlinear partial differential equations to the general nonlinear parabolic equation for a complex amplitude of an envelope wave. The equation is complexly derived: by using wave packages, meth

For the development of finite element schemes, a fundamentally new system of test functions defined on a finite element that is a convex quadrilateral is proposed. Due to the remarkable properties of the system (specifically, mutual orthogonality), t

A mathematical model is presented that describes the relative motion and heart exchange of a fine spherical particle of variable diameter in a heterogeneous carrier medium under conditions of nonisothermal free convection of the inhomogeneous heterog

A mathematical model describing a rotary cycloid device containing a rotor and stator with effective surfaces built in the form of a cycloid is proposed. The mathematical model is based on equations of explicit form for skewed hypocycloids, which des

A model of turbulent heat and mass transfer with nonlinear sources for the modeling of fast poly-merization processes under matching conditions (equality of the values of temperatures and local flows) on the reactor—coolant interface was developed.

A mathematical model has been constructed for the motion of multiphase heterogeneous media over the surface of rotating extension pieces and in hydrocyclones. The model takes into account the separation and thickening of the medium and the existence
