EXPERIMENTAL STUDY OF MASS TRANSFER COEFFICIENTS AND FRICTION FACTOR INSIDE A BUNDLE AS A FUNCTION OF THE YAW ANGLE.

Summary

THE DEVELOPMENT OF THE LOCAL MASS TRANSFER COEFFICIENT AROUND A CYLINDER PLACED IN A PIPE BUNDLE AS WELL AS THE OVERALL VALUE ARE STUDIED EXPERIMENTALLY ; FLOW HAS A VARYING YAW ANGLE: 0, 22.5, 45, 60 AND 90 DEG ; THE REYNOLDS NUMBER RANGES BETWEEN 10,000 AND 100,000. BY ANALOGY, A LAW OF OVERALL HEAT TRANSFER IS DEDUCED. A LAW OF PRESSURE DROP IS ALSO PROPOSED AS A FUNCTION OF THE YAW ANGLE AND THE EFFECT OF PLATE GRID ON THE EXCHANGE COEFFICIENT IS CHARACTERIZED.
