Summarisation of experimental data on the intensity of heat transfer in a contact device made of pipe turbulation systems with spiral turbulation generators

This article presents experimental data on heat transfer during contact between the gas and liquid phases using a contact device consisting of a tube bundle with spiral turbulators.It has been established that this method can intensify the heat exchange process and align the temperature along the height of the strengthening section of a distillation column.Experimental data on heat transfer during direct phase contact using an efficient contact device consisting of a tube bundle with periodically arranged turbulators have been obtained.It has been found that turbulators of this design increase the turbulence of the contacting phases, and heat transfer has been intensified by a factor of 1.5 or more.A criterion formula in the form of a highly accurate functional dependence, Ki = f(Re liquid , Re gas , Pr gas , s/d, t/d, Re к ), has been derived from the experimental data.Its error does not exceed ±5,0%.
