...S. K. Saha; A. Dutta Heat transfer and pressure drop characteristics in a circular tube fitted with twisted tapes have been investigated experimentally. Laminar swirl flow of a large Prandtl number 205 < Pr < 518 viscous fluid was considered. The swirl was generated by short-length twisted...

...S. V. Ekkad, Assistant Professor, Assoc. Mem. ASME; G. Pamula, Graduate Student, Mem. ASME; S. Acharya, L. R. Daniel Professor, Fellow ASME Detailed heat transfer distributions are presented inside a two-pass coolant channel with crossflow-induced swirl and impingement. The impingement and passage...

...J.-J. Hwang; C.-S. Cheng Measurements of detailed heat transfer coefficients on two principal walls of a triangular duct with a swirling flow are undertaken by using a transient liquid crystal technique. The vertex corners of the triangular duct are 45, 45, and 90 deg. The swirl-motioned airflow...

...Hui-Ying Wu; Hui-Er Cheng; Ren-Jun Shuai; Qiang-Tai Zhou Decaying swirl flow can enhance the heat transfer inside a tube. For the decaying swirl flow of which maximum tangential velocity is located in the immediate vicinity of the wall, an analytical model based on the fluid theorem about...
