Measurement of Fully Developed Turbulent Flow through Rectangular Duct with Roughened Short-Side Walls.

Fully developed turbulent flow through three concentric annuli was investigated experimentally for a Reynolds-number rangeRe= 2 × 104−2 × 105. Measurements were made of the pressure drop, the positions of zero shear stress and maximum velocity, and the velocity distribution in annuli of radius ratios α = 0.02, 0.04 and 0.1, respectively. The results for the key problem in the flow through annuli, the position of zero shear stress, showed that this position is not coincident with the position of maximum velocity. Furthermore, the investigation showed the strong influence of spacers on the velocity and shear-stress distributions. The numerous theoretical and experimental results in the literature which are based on the coincidence of the positions of zero shear stress and maximum velocity are not in agreement with reality.

A previous paper gave an account of a method of calculating the velocity of deposition of aerosol particles upon the wall of a pipe through which they were passing in fully developed turbulent flow. This is now extended to include small particles which diffuse at an appreciable rate owing to their Brownian motion.

Fully Developed Turbulent Flow

A mixing length model for fully developed turbulent flow in rectangular ducts has been developed. In this model, the mixing length at any point is found from an algebraic combination of two mixing lengths, one for each set of parallel walls. The model correctly predicts the overall friction and heat transfer in a channel as well as in a rectangular duct.
