本研究项目的目标是通过实验，开发无量纲压降和传热关联式，可用于预测5000至1000000雷诺数范围内的内翅片管的性能，包括单相制冷剂和商业用途的管的油和无油。需要低至5000的液体雷诺数才能正确确定制冷剂的热物理性质，并在过渡雷诺数和湍流雷诺数范围内验证实验装置。

The objective of this research project is to develop, through experimentation, non-dimensional pressure drop and heat transfer correlations which may be used to predict performance of internally finned tubing through a 5,000 to 1,000,000 Reynolds number range with and without oil for single-phase refrigerants and tubes of commercial interest. Liquid Reynolds numbers as low as 5,000 are required for proper refrigerant thermophysical property determination and to verify the experimental facility across a range of transitional and turbulent Reynolds numbers.
