Parametric Study on Performance of Straight Type of Internally Finned Tube
The performance of a straight type of internally finned tube (SIFT) is studied using computational fluid dynamics (CFD). It is found that a longer fin yields a larger pressure drop that is nearly proportional to the fin length. When the fin length is larger than 30 d, the pressure drop is greater th...

| Summary: | The performance of a straight type of internally finned tube (SIFT) is studied using computational fluid dynamics (CFD). It is found that a longer fin yields a larger pressure drop that is nearly proportional to the fin length. When the fin length is larger than 30 d, the pressure drop is greater than that of a bare tube. The temperature uniformity decreases with the fin length of the SIFT. Furthermore, a smaller fin angle yields a larger pressure drop, while a larger fin angle yields better temperature uniformity. A larger contraction yields a larger pressure drop, too. |
