Abstract
A spiral flow is the resultant of primary and secondary flows; in a regular circular pipe, spiral flow does not exist. There are two methods of generating spiral currents in a closed conduit: (1) installing helical ribs inside regular circular pipes and (2) using noncircular pipes. Characteristics of spiral solid- liquid flows generated by these two methods are studied and compared with those of regular circular pipes. The critical deposit velocity and the head loss at various flow velocities in each pipe are compared and analyzed. The results show that there is a good possibility that square pipes may be used to replace the traditional pipes for the transport of solids.
