The dispersion of smoke puffs has been used as a method of measuring turbulent diffusion in the atmosphere. Some of the basic equations of turbulent diffusion as applied to the dispersion of small-scale smoke puff and are recalled. The intensity of t

The equation of decay of isotropic turbulence is determined in the two cases of large and small Reynolds number of turbulence by using the von Kármán-Howarth equations and applying Loitsianskii’s theorem of the conservation of the disturbance mom

The IMFL anemoclinometer is an instrument measuring the magnitude and direction of a fluctuating fluid velocity. As a result of a measurement, three pressure differences are obtained from which the vector velocity is found. Contrary to some similar i

Turbulent diffusion from an infinite line source in a homogeneous, stationary, non-isotropic turbulent flow is studied. Spatial mean-concentration distributions are determined as functions of the statistical characteristics of turbulence. Particular

SummaryThe paper discusses the influence of wire length on the characteristics of a turbulent flow as measured with a hot-wire anemometer. Most of the mathematical treatment can be directly applied to other problems of length correction, such as may

A conventional anemometer used in the atmosphere or in a wind tunnel measures velocities projected on a plane independently of their directions in the plane. The relation between the frequency distribution of those velocities and the frequency distri
