Experiments and numerical simulation are performed to investigate the mechanism of heat and mass transport inside a ribbed tube induced by reciprocating flow. The reciprocating flow is generated by a crank-piston device without producing a net throughflow. It is disclosed from the study that the reciprocating flow causes the generation and extinction of separation vortices behind each rib to manipulate "trap and release" mechanism of heat and mass transport in the axial direction. The transport performance thus produced inside the ribbed tube is far superior to those inside the smooth tubes or so-called dream pipes.
