- •
A novel helical baffle heat exchanger with elliptical tubes was developed and tested.
- •
Heat transfer performance in the elliptical tube heat exchanger was numerically studied.
- •
Performance comparison of elliptical tubes with circular tubes was investigated numerically.
- •
Elliptic tube can effectively improve the heat transfer performance.
- •
The correlations for Nu and f in the shell side of the elliptic tube heat exchanger were proposed.
