With the development and utilization of offshore liquefied natural gas, it is increasingly important to study the influence of the heat transfer performance of a spiral-wound heat exchanger under sloshing conditions. This study focused on the effects of different sloshing amplitudes and sloshing periods on the heat transfer and pressure drop performance of a heat exchanger. Through experimental research, the results showed that the fluctuation of the UA (U is the heat transfer coefficient; A is the heat exchange area) value first increased and then decreased with an increase in the sloshing amplitude. The UA value increased by 12.92% and decreased by 42.03% compared to the static value at 3 and 9°, respectively. The fluctuation in the UA value first decreased and then increased with an increase in the sloshing period. The UA value decreased by 36.66% and increased by 10.82% slowly compared to the static value when the sloshing period was 6 and 20 s, respectively. Based on this, a mathematical model of heat transfer under the condition of pitch sloshing was established.

“…For example, Vocale [3] considered the coupled heat transfer of spiral tubes and evaluated the influence of the selection of thermal boundary conditions on the local heat transfer phenomenon in coils. Ren [4] , Lu [5] and Zeng et al [6] analyzed the influence of different boundary conditions and different geometric parameters on the conjugate heat transfer of spiral tube heat exchangers, and concluded that curvature, pipe diameter and grid thickness are the main factors for the optimal design of heat exchangers. Sun [7] and Yu [8] explores the shell side flow and heat transfer characteristics of spiral wound heat exchangers in floating liquefied natural gas, including experimental research on the influence of tilt, yaw and pitch on the pressure drop of spiral wound heat exchangers.…”

In view of the complex structural characteristics and special operating environment of the horizontal spiral tube heat exchanger of the shaft sealed nuclear main pump, the numerical simulation method of flow heat coupling is used to analyze the influence of the flow and temperature changes of the fluid on the shell side on the flow field and temperature field of the heat exchanger, explore the influence rules of the inlet parameters on the flow and heat transfer characteristics of the fluid in the heat exchanger, and analyze the enhanced heat transfer performance of the heat exchanger by using the relevant heat transfer criteria. The results show that the horizontal spiral tube fluid generates centrifugal force under the influence of curvature, forming a secondary flow which is different from the straight tube flow heat transfer, and the velocity distribution is concave arc, which will enhance the heat transfer efficiency of the heat exchanger; with the increase of shell side velocity, the degree of fluid disturbance and turbulence increases, while the pressure loss does not change significantly, and the heat transfer performance of the heat exchanger increases; under the given structure and size, the heat transfer performance curve of the heat exchanger shows that the increase of shell side flow and Reynolds number has a significant impact on the enhanced heat transfer of the spiral tube. In practical engineering applications, the heat transfer can be strengthened by appropriately increasing the shell side flow of the heat exchanger.
