- •
A three-dimensional model of U-tube GHE is established and performed by CFD.
- •
The fluid temperature along the pipes for different factors is discussed.
- •
Totally 101 cases are carried out in order to study the influence on GHE.
- •
A best-fitting correlation with 9 variables is obtained by multiple regression and validated by experiment.
