AB  - The heat transfer characteristics of propylene glycol-water (PG-W) mixture with different concentrations in shell side of spiral wound heat exchanger 
(SWHE) with different geometric parameters were studied numerically. Experiment was carried out and the average difference between the simulated 
results and the experimental results was 5.3%. The simulation results show that heat transfer coefficient increases with the increase of center core 
diameter and longitudinal spacing of tubes, but decreases with the increase of tube outer diameter. The center core diameter and tube outer diameter 
have greater effects on heat transfer performances at higher concentration. Economic index was established and found that adding materials for changing 
center core diameter and tube outer diameter will improve economic index. While adding materials for changing longitudinal spacing of tubes will 
reduce economic index. Adding materials for changing center core diameter has higher cost performance. The results can provide reference for the 
design of gasifier in the gas supply system of dual fuel engine.
