- Abstract:
-
The two layers tube model of spiral tube heat exchanger with different tube diameter (6mm<d0<14mm), different thickness of space bar(2mm<S2<4.5mm), and different tube pitch(2mm<Z<14mm)was study for the structure parameters of the spiral tube heat exchanger. Water was used as the heat transfer fluid, and the numerical simulation research about the characteristics of heat transfer and flow of the shell side fluid of the spiral tube heat exchanger was carried out by using Realizabl κ-ε model of Fluent software.The influence of tube diameter, thickness of space bar and tube pitch on Nusselt number,synergetic number,entransy loss rate, entransy thermal resistance,and comprehensive heat transfer performance evaluation factor was analyzed. The experimental model was made by combining the numerical model;and the performance test was carried out.The research results showed that the comprehensive heat transfer performance evaluation factor of the spiral tube heat exchange could reach the maximum when the pipe diameter was 6mm, the thickness bar was 3.5mm,and the tube pitch was 14mm.The difference between the simulation results and the experimental data of temperature and pressure drop was1~4℃，0.8~1.2kPa.
