AbstractIn this article formulation of MI simulation and equations of linearized error dynamics and eigenvalue analysis of MI simulation were first explained. Example of MI simulation was presented for a fully developed turbulent flow in a square duct. Numerical experiment was performed for MI simulation with a feedback signal from the predetermined standard turbulent flow solution. Convergence of MI simulation to the standard solution was investigated as a function of feedback gain and spatial and temporal density of feedback signal. Eigenvalue analysis was performed to examine the validity of the linearized error dynamics approach in the design of feedback signal.
