Speed Distribution in the Transverse Profile of the Measurement Duct

On the initiative of staff of Ohře River Authority, a theoretical exploration on the speed distribution in a transvrese profile of a measurement duct was conducted. Publications on hydrology present the speed distribution along the height of...

Influence of the Wall Roughness on the Wind Profile and Concentration of Pollutants in the Atmosphere

Numerical modelling and also wind tunnel experiments dealing with atmospheric flow and pollutant dispersion require a proper definition of the mean wind profile. For neutral conditions the wind speed varies logarithmically with heig...

Indirect determination of the turbulent velocity profile origin

The vertical co-ordinate of the logarithmic turbulent velocity profile origin yo is an important characteristic of turbulent flow in conduit with rough walls. Because length and height of saltation depend strongly on the position of...

Shape of velocity distribution near the bottom with high values of realtive roughness

Shape of velocity distribution in 2D stationary uniform fully turbulent flow with free surface is logarithmic in range from the level near the bottom to the level 0,2h, but out of this range is not. Near the bottom is the shape of velocity <...

Matrix logarithmic quantum wave equation

Quantum wave equations with logarithmic nonlinearity are motivated by the conventional (linear) quantum formalism and theory of quantum liquids. The matrix generalization of the logarithmic equation is introduced, which is expected ...
