Abstract:

THE DEMAND FOR A COMPACT HEAT EXCHANGER IS GROWING, AS MANY INDUSTRIES INCLUDING AUTOMOTIVE, ELECTRONICS, HEAT RECOVERY AND OTHERS, ARE FORCED TO MEET THEIR INCREASING HEAT FLUX DENSITY REQUIREMENTS. CURRENTLY, VARIOUS HEAT TRANSFER AUGMENTATION CONCEPTS ARE BEING USED IN INDUSTRIES FOR HEAT TRANSFER ENHANCEMENT, AND MOST OF THE CONCEPTS DEPEND ON BOUNDARY LAYER CONTROL AND INCREASE OF THE HEAT TRANSFER SURFACE. HOWEVER, THIS APPROACH HAS LIMITATIONS DUE TO THE HIGH PRESSURE DROP PENALTY AS A DIRECT RESULT OF APPLYING THE AUGMENTATION DEVICES. RECENT HEAT TRANSFER STUDIES OF AN ANNULUS OR A DUCT, ONE WALL OF WHICH IS IN MOTION TRANSVERSELY WITH RESPECT TO THE AXIAL FLUID FLOW, SHOWED THAT A SIGNIFICANT INCREASE IN THE HEAT TRANSFER COEFFICIENT IS POSSIBLE WITH A MODERATE PRESSURE DROP IN THE FLOW DIRECTION. THE OBJECTIVE OF THE PROPOSED WORK IS TO STUDY EXPERIMENTALLY THE HEAT TRANSFER AND PRESSURE DROP CHARACTERISTICS OF THE ANNULUS OF TWO CONCENTRIC CYLINDERS WITH THE INNER CYLINDER (GROOVED OR UNGROOVED) ROTATING, WITH THE AIM OF MAKING A FEASIBILITY STUDY OF A NOVEL HEAT EXCHANGER. POTENTIAL IMPACT OF THE HEAT EXCHANGER ON ON AEROSPACE, AUTOMOTIVE, AND ELECTRONIC INDUSTRIES IS EXPECTED TO BE VERY HIGH.
