Summary

THE TUBE ARRAYS CONSIDERED ARE AN IN-LINE TUBE ARRAY AND A STAGGERED TUBE ARRAY. THE FLUID AND TUBES ARE CONSIDERED TO BE AT THE SAME TEMPERATURE, EXCEPT FOR THE ARRAY TUBE, WHICH IS HEATED OR COOLED. THE SOLUTION DOMAIN COVERS 3 PITCHES OF TUBE ARRAYS. THE HEAT TRANSFER IN A STAGGERED ARRAY IS FOUND TO BE HIGHER THAN THAT IN AN IN-LINED ARRAY. THE PRESSURE DROP IN A STAGGERED ARRAY ARRANGEMENT IS ALSO HIGHER. AT HIGH REYNOLDS NUMBER, THE LOCAL HEAT TRANSFER TENDS TO PEAK AT THE UPSTREAM SURFACE OF THE HEATED TUBE BUT AWAY FROM THE STAGNATION POINT AND BECOMES MINIMUM AT THE SEPARATION POINT.
