Abstract
Transition from laminar to turbulent flow in tubes with longtitudinal internal fins has been examined theoretically using Hanks’ criterion. The critical Reynolds number is a strong function of the ratio of fin height to equivalent diameter, X/De. The agreement with the experimental data is good. A regression equation for the critical Reynolds number as a function of X/De is given.
