Numerical simulation on optimization of fairing device for airflow measurement

Accurate measurement of air flow is important for safe and economical operation of power plant. The straight tube before and behind measurement instrument usually can not meet the demands because of the design and installation condition, which affect the measurement accuracy. Flow field, Pressure and velocity distribution of airflow duct with Fairing device is studied in this paper. The optimization for dimension, structure and installation position of the fairing device are carried out by numerical simulation method.
