SIMPLE METHOD OF PREDICTING FRICTION FACTORS OF TURBULENT FLOW IN NONCIRCULAR CHANNELS

A method is developed which allows the prediction of friction factors for turbulent flow in non-circular channels if only the geometry factor of the pressure drop relationship for laminar flow is known. The proposed method of calculation is tested with numerous experimental results from the literature with respect to non-circular channels such as triangular shaped ducts, eccentric annuli and rod bundles in hexagonal and square arrays in circular tubes, hexagonal and square channels.
