PATTERNS OF FLUID FLOW IN A SHELL-AND-TUBE HEAT EXCHANGER.

Author(s) : PEREZ J. A., SPARROW E. M.

Type of article: Article

Summary

THE OIL-LAMPBLACK TECHNIQUE WAS EMPLOYED. FLOW PATTERNS WERE VISUALIZED ADJACENT TO THE SHELL WALL, TO THE BAFFLE PLATES, AND TO EACH TUBE OF THE ARRAY. FROM THE FLOW PATTERNS ADJACENT TO THE SHELL, THREE RECIRCULATION ZONES WERE IDENTIFIED. THE PATTERNS ADJACENT TO THE BAFFLES WERE SIMILAR TO THOSE FOR CROSSFLOW OVER A TUBE BANK, WITH CURVATURE-RELATED DEVIATIONS NEAR THE SHELL. THE FLOW PATTERNS ADJACENT TO THE TUBES SHOWED, TYPICALLY, A STAGNATION LINE/CIRCUMFERENTIAL FLOW SYSTEM ON THE UPSTREAM FACE OF EACH TUBE AND A RECIRCULATION ZONE DOMINATING THE LEE SIDE.
