SOME FEATURES OF THE TEMPERATURE FIELD, CREATED BY THE LOCAL TURBULENT REGION INTO STRATIFIED MEDIA

摘要

Density stratification effects on a free turbulent current is escorted by a collapse of turbulent area. This phenomena result to axial asymmetry of current, to change of laws of degeneration of hydrophysical fields and origin of secondary currents. Information on internal space structure of hydrophysical fields in such flows are rather limited. The problem on effect of conditions of an environment, in particular such as stratification on character of development of a flow of a liquid is insufficiently probed also. The main task of the present research is the field of the temperature initiated by limited degenerating turbulent area in temperature a stratified medium. The effect of the stratification on development of temperature field is investigated. Definition of temperature in different points of space are effected by a multipoint measuring complex with sensitive detectors as which thermocouples about a diameter about 0.2/0.3mm are used. Visual representation as temperature depth variations, isotherms or field changes on the given horizons is carried out the appropriate software. Experimental data on statistical characteristics, and space structure of a temperature fluctuation field of area are obtained. The cross-correlation analysis results have allowed to estimate space scales of heterogeneity's of afield of temperature.
