The Research of Auger-Type Heat Exchanger Fluid Characteristic Based on FLUENT
The auger-type heat exchanger possesses many merits, such as compact structure, high thermal efficiency, and is mainly used in food, oil, natural gas and chemical industry. The shell-side fluid characteristics are calculated through FLUENT based on computational fluid dynamics (CFD) theory, and the typical regional and cross-section of the shell-side fluid are analyzed in detail. The results show that current "dead zone" exists in the head of the receiver at the entrance and the core body, which is not conducive to the efficiency and service life of the heat exchanger, and a large pressure exists on the outer heat transfer tubes at the entrance, which leads to the erosion.
