Laminar Flow Heat Transfer in a Pipe Preceded by a 180� Bend
Abstract
Experiments were conducted to study heat transfer mechanisms in laminar flow in a pipe preceded by a U-bend. The ll-bend had a curvature. ratio (Rc/ri) of 7.66. Ethylene glycol was used as a test fluid. Straight sections of the tube were heated by passing DC current through the tube wall. The local heat flux was approximately constant for each run. Local outer surface temperatures were measured peripherally along the test section. Reynolds numbers ranged from 62 to 528 while Prandtl numbers ranged from 75 to 132.
