The different variants of the Navier -Stokes equations are presented in the paper. The authors also present new variants to be used for qualitative analysis of the fluid [...]

It is generally known, that liquids, including water, are electrically conducting. The electric conductivity magnitude among others depends on the minerals concentration. [...]

This paper is focused on the study of the second viscosity of the fluids with the emphasis on the pressure pulsations solution in the hydraulic systems. The methodic come [...]

In all areas of the technical creative work we do meet the design and planner engineers’ tendency of lowering the device’s power input in the power output conservatio [...]

This paper presents a variant of a mathematical model of continuum mechanics. Adaptation of the model is focused on unsteady term. The solution is based on the assumption [...]
