Process and apparatus for enhancing in-tube heat transfer by chaotic mixing

摘要

A process and apparatus for enhancing in-tube heat transfer within a tubular member. A fluid is introduced into the tubular member and then directed in a downstream direction through a coil of the tubular member. The first coil defines a first coil axis. The fluid is further directed in the downstream direction through at least one downstream coil. Each downstream coil has a coil axis which is rotated at a coil switching angle, with respect to the coil axis of the immediately upstream coil. The fluid is maintained at a turbulent flow level within at least a portion of a coiled section of the tubular member. The fluid is then discharged from the tubular member.
