Next, the mean velocity field, the turbulent kinetic energy field, the mean concentration field and the concentration fluctuation field are presented and analyzed.
It is better to apply this concept to the ensemble of growing nuclei as a whole since this leads in a natural way to the definition of a uniform diffusion layer, which is connected with the idea of a mean concentration field.
(a) Mean CO2 concentration field at 250 hPa for June 2007, as simulated by NICAM-TM, and the locations of the CONTRAIL measurements for 2007 (white dots).
Measurements of mean and fluctuating velocity and temperature fields, mean concentration of major chemical species, correlation between velocity and temperature fluctuations, and dissipation of temperature fluctuations are reported in a turbulent round jet non-premixed propane flame, Re=20 400 and 37 600, issuing vertically in still air.
The mean concentration of iodide in field soil ranges from 5 to 20 mg/kg in dry soil, and around 2 mg/kg dry soil in paddy soil [ 31].
The flow field, the mean concentration and the variance of a flow over a two-dimensional triangular hill, with a finite-size point pollutant source, are calculated by a finite volume code and compared with published experimental results.
The developed theory is used to quantify the effects of mean concentrations on the field scale coefficients of decay, retardation and macrodispersion, and to evaluate the assumption of a steady-state biomass, previously reported in the literature.
Where field duplicate data exists, we calculate and plot the mean concentration or value for that location.
It can mean concentration.
Each bar represents the mean concentration ± SD.
