Abstracts:

During this work have been investigated the formation of spatial convective structures in the zone of mixing of two miscible fluids impingement on each other. It was found that when vertical channel of rectangular cross section translated in a horizontal position, which filled with layered system of fluids, a longitudinal density gradient occurs, that leads to a counter-movement of fluids with the development of secondary flow in the area of mixing in the form of small-scale parallel ridges along the direction of the fronts. It was render front propagation displacement of the secondary flow in horizontal and vertical cross sections along the horizontal canal. Was studied behavior of the secondary convective structure and the front propagation mechanism of repression.
