Interfacing Stereoscopic PIV measurements to Large Eddy Simulations via Low Order Dynamical Systems

摘要

An original method consisting in interfacing dual-time Stereoscopic PIV measurements to a numerical code is proposed to provide inflow data to numerical simulations. It relies on the use of the Proper Orthogonal Decomposition to model the temporal dynamics of the coherent structures of the flow via a low order model and adapt the experimental mesh to the numerical one. LES of a turbulent plane mixing layer is performed to demonstrate the viability of the method.
