Heat transfer in a channel with spherical intensifiers where a non-azeotropic alcohol-water mixture circulates

Passive intensification of heat transfer in a tube is achieved by using detachable intensifiers or changing the shape of the heat transfer surface. In this work, the intensification process was studied using spherical turbolizers located in a horizontal stainless steel channel. Experimental data were obtained during circulation of an alcohol-water mixture with a concentration of 30% wt. at a pressure in the vessel of 0.03-0.04 MPa. It is shown that the efficiency of spherical intensifiers is commensurate with the efficiency of spiral intensifiers at significantly lower pressure drops.
