Abstract
An estimative hydrodynamic calculation of liquid mixing in a cylindrical tank in a turbulent mode, occurring at pumping of an amine water mixture in and its simultaneous pumping out, has been performed. A high inlet jet velocity provides a turbulence cone practically reaching the opposite wall of the tank. Stirring parameters, including the turbulence cone size and components of the liquid flow velocity inside and outside of the turbulence cone have been determined. It is shown that for given parameters it is impossible to form an area near the inlet and outlet openings where the incoming liquid would immediately be removed by the out-going flow from. Contrary to this, there are circumstances under which the existence of such a region would be possible, namely, inhibiting the mixing “interception” would occur, where the fluid outlet positioned in the area opposite to the inlet opening within the cone of turbulence. Effective interception of the inlet flow at given relative positions of inlet and outlet orifices can take place at certain parameters corresponding to a laminar liquid flow. The advantages of the physical calculation over the purely engineering one are shown to be the ease of scaling and the transparency of factors affecting the final result.
