Abstract— The occurrence of turbulent pulsations in straight pipes of noncircular cross-section leads to the situation, when the average velocity field includes not only the longitudinal component but also transverse components that form a secondar

Turbulent flow in a tube of square cross section is investigated numerically. The concentrated longitudinal vortices responsible for the occurrence of secondary flows are studied. It is shown that the longitudinal vortices are formed as a result of n

Disturbance evolution in developed turbulent flows in a plane channel is numerically investigated at the Reynolds numbers up to Reτ = 586. Steady turbulent flows calculated on the basis of the solution of the incompressible Navier—Stokes equations

New methods of interpretation of meteor observations were developed and published in [1–9]. The interpretation of ground-based observations of meteors and bolides available today in the scientific literature all over the world suffers from serious

The existing methods for determining the extra-atmospheric mass of meteor bodies from observations of their movement in the atmosphere allow a certain arbitrariness. Active attempts to overcome the discrepancy between the results of calculations base
