Abstract: The known gyroscope theory based on principle of the rate change in the angular momentum of a spinning rotor. Practice demonstrates this mathematical model cannot describe other gyroscope effects and shows that there are other unsolved problems, which is spawned steady myth of the gyroscope mystery. These phenomena attract new researchers to solve gyroscope problems. The nature of gyroscope effects is more complex that represented in publications and known mathematical models do not match the actual motions and forces of the gyroscope effects. Latest studies of forces that involved in motions of a gyroscope demonstrate that there are four dynamical components, which act simultaneously and interrelated with others. The gyroscope with the external torque applied is experienced the resistance torque generated by the centrifugal and Coriolis forces and the precession torque generated by the inertial forces and the rate change of the angular momentum of the spinning rotor. These four dynami

Abstract: Numerical simulation of multi-component flows is a challenging task. It requires dealing with mathematical models, numerical solution techniques, uniformity and nonuniformity of the physical and thermodynamic properties of the flow component and the dynamic changes of the interfaces. In this contribution a numerical application is developed to solve a pressure non-equilibrium multi-component model. The numerical solution is based on a finite volume scheme and the interface is treated as a diffuse zone with a small controlled thickness. Since each flow component has its own pressure, a pressure relaxation procedure is considered during the solution. The code is verified against benchmark tests in one and two dimension flows. The results show very good agreement with the reference data, which proves the capabilities of the developed numerical tools.
