摘要：

Measurement-integrated simulation (MI-simulation) is a numerical simulation in which experimental results are fed back to the simulation. The calculation becomes closer to those of the experiments. In this paper, MI-simulation employed a turbulent model is applied to steady and unsteady oscillatory airflows passing an orifice plate in a pipeline. Velocity and pressure feedback are conducted and both feedback method showed good agreement with experimental results. Moreover, comparisons of calculation time were performed between MI-simulation and the ordinary simulation in steady and unsteady conditions. It was demonstrated that the calculation time was significantly reduced compared to the ordinary simulation.
