RESUMO

The article is concerned with the process of heat transfer in a "pipe-in-pipe"-type apparatus, where the inner pipe is filled with a fine chaotic packing serving as a volumetric intensifier. In the pipe filled with the packing, the turbulent regime starts an order of magnitude earlier than the motion of heat carrier in smooth pipes without intensifiers. A change of regime is especially important when heating or cooling high-viscosity media takes place. In the article, the process of heat transfer in the apparatus filled with a chaotic packing when the industrial oil is heated through the separating wall of the pipe with hot water is investigated experimentally. Experimental values of heat transmission and heat transfer coefficients were obtained and it was shown that the intensification caused the increase in the heat transfer coefficient by 14 times or more. The experimental and calculated heat transfer coefficients were compared using an expression obtained by means of the two-layer model of turbulent boundary layer. Using the cell model of the flow structure, we calculated the temperature profiles of the oil; the profiles showed a good (± 1.5%) agreement with the experimental values. The obtained experimental data and the mathematical model can be used to modernize or design intensified heat exchangers in various branches of industry and in power engineering.
