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... https://www.ngetikin.com/super-value-1-2-in-Tobacco-Road-Acacia-Distressed-Engineered-Hardwood-Flooring-4-8-in-Wide-Sample-quick-super/
