Summary

EXPERIMENTS WERE PERFORMED TO INVESTIGATE THE SENSITIVITY OF THE HEAT TRANSFER COEFFICIENT FOR AN ANNULAR FIN TO SMALL ANGLES OF ATTACK (-2 TO + 2 DEG). MEASUREMENTS WERE MADE ON THE FIN SURFACE: (I) FORWARD OF THE TUBE ; (II) AT THE SIDE OF THE TUBE ; AND (III) BEHIND THE TUBE. THE HEAT TRANSFER COEFFICIENT IN ZONE (I) WAS HIGHLY SENSITIVE TO THE ANGLE OF ATTACK (+ 50%). THE CORRESPONDING INCREASES IN ZONES (II) AND (III) WERE ABOUT 10%. FOR ANY ANGLE OF ATTACK IN THE INVESTIGATED RANGE, THE TWO-FACE AVERAGE FOR EACH ZONE WAS NOT VERY DIFFERENT FROM THE HEAT TRANSFER COEFFICIENT FOR ZERO ANGLE OF ATTACK.
