The aim of present experimental research is to find out the suitable correlations for designing the internally finned heat exchanger used in cryogenic applications. In order to conduct above experimental study, different size of internally finned heat exchangers were developed and tested in cryogenic environments. The experiments were conducted in the range of velocity varies from 0.001m/s to 0.14m/s. The effect of finned clearance on the prediction of overall heat transfer coefficient is also investigated experimentally. The results from present study were compared with these calculated from empirical equations. From the present experimental results, a more accurate new correlation has been formed using in cryogenic situations.
