The use of a pulsating flow of the heat carrier for the intensification of heat transfer in plate heat exchangers in the production of liquid nitrogen fertilizers

The article describes a method for improving the quality of produced liquid complex fertilizers by intensifying heat exchange using a pulsed flow of liquid in plate heat exchangers. The article is devoted to the question of the influence of impulse flow on the intensification of heat transfer in plate heat exchangers. Analysis of the literature shows that the increase in heat transfer is influenced by such factors as the shape of the channel, the location of the pulsation generator, as well as their amplitude and frequency. Changing the shape and pattern of the plates allows you to increase heat transfer, due to the receipt of greater flow turbulization. The results of the study of the heat transfer coefficient at various pulsation frequencies and coolant flow rates are also considered, from which the dependence of the heat transfer intensity on the pulsation frequency of the generator itself is visible.
