Abstract

In the greenhouse gas emission monitoring from industrial stacks, S-type Pitot tube is the most commonly used to measure the stack gas velocity. Various factors such as Reynolds number, misalignment of installation angle can be additional error sources for the S-type Pitot tube coefficients due to harsh environments. In present study, wind tunnel experiments were conducted to examine the effects of various factors on the S-type Pitot tube coefficients. Numerical simulations were also used to understand flow phenomena around S-type Pitot tube when misalignment and distortion of geometry happen.
