An experimental and numerical study oj turbulent air flow in circular section pipe bends was carried out in order to determine the f influence o bend curvature on theflow.
Two bends were used, with inside diameters o 43 mm and curvature ratios o 1 :13.95 and I :6.98. The corresponding Dean numbers f f were 9138 and 12 919. The Reynolds number for both cases was 34 132.
Measurements o mean streamwise and r.m.s. velocities were made using laser Doppler anemmetry. Numerical modelling was based on f the commercial computer package 'PHOENICS', employing a k-& turbulence model, standard wall functions and a
