Measurement-integrated (MI) simulation is a numerical simulation in which experimental results are fed back to the simulation. The calculated values become closer to the experimental values. In this paper, MI simulation using a standard k-ε model is proposed and applied it to steady airflows passing an orifice plate in a pipeline. The upstream corner tap pressure in simulation is compensated by using proportional controller or proportional-integral controller. The signal is fed back to the axial velocity control volume in vena contract. The effectiveness of the method was evaluated compared with the experimental results at downstream of orifice. The calculation time of proposed MI simulation is significantly reduced compared with ordinary simulation analysis.
