Abstract

The downstream flow of 90°single bend was investigated by computational fluid dynamics (CFD). An acoustic transit time flowmeter was exposed to the downstream flow at various positions. Measurement errors with different meter configurations and effects of pipe wall roughness were discussed. Numerical simulation results of three diameter pipes 0.1 m, 1 m and 10 m with increasing the roughness from 0 to 1 mm were presented within Reynolds number (Re) range from 5 × 10³ to 5 × 10⁶.
