A mathematical modeling of rotating waves in axial and radial compressors
Archive of Applied Mechanics, 1996A comparison between meteorological systems and fluid motions through compressors is proposed. A mathematical analysis analogous to the geophysical one emphasizes characteristic dimensions. A dimensionless kinematic parameter, akin to the Rossby number, emerges, and thus leads to the study of different cases.

Mathematical model of the cylinder rotations in a viscous medium
AIP Conference Proceedings, 2014In the paper movement of a rotating cylinder in a viscous medium is considered. Control law provides given position of the cylinder at the finite time minimizing the work of the drag forces to rotation is found. In the case when the control force is applied in the direction of the axis of symmetry the problem is singular.

Some aspects of the mathematical modeling of the earth rotation
Advances in Space Research, 2002Abstract A numerical theory of the rigid Earth's rotation taking into account the most essential relativistic perturbations (geodetic perturbations) is developed using improved initial conditions of the numerical integration. The differential equations of the rigid Earth's rotation are solved using the Rodrigues-Hamilton parameters, which describe ...

The Mathematical Theory of the Motion of Rotated and Unrotated Rockets
Nature, 1949VERY little of a vast literature on rocket research has yet been published in book form or as papers in scientific journals. This is perhaps inevitable, since the development of the modern rocket has been due to the requirements of the War, and the numerous existing reports and papers, in many fields of scientific and technical endeavour, still carry a

A GENERALIZED MATHEMATICAL MODEL FOR ROTATING ELECTRICAL MACHINES
1986The aim of the paper is to present a mathematical model useful to analyze the different operating conditions of the different structures of rotating electrical machines. For this purpose it is first shown that the same mathematical expression describes the air gap m. m. f.
