摘　　要：This paper performs experiment on heat transfer and pressure drop in different 3-D internally finned tubes, investigates the transition from critical zone to transition zone. Four expressions about the Reynolds criterion for transition, the largest Fanning friction factor, the Nusselt number and Fanning friction factor have been obtained respectively.This paper performs experiment on heat transfer and pressure drop in different 3-D internally finned tubes, investigates the transition from critical zone to transition zone.
