Visualizing the state of real turbulent flow is important in many applications such as safe operation and diagnosis of fault in plant or pipeline. However, visualization of flow field is difficult in many actual cases. We target a visualization of an oscillating air flow through an orifice, which is widely used in industry, in a circular pipe. As a visualization method, measurement-integrated (MI) simulation using a standard k-ε model is employed to reduce computation time. In this paper, we induct the apparatus of our MI simulation by comparing with experiment and ordinary CFD analysis in steady and unsteady condition.
