The models are<br /> based on the method of Proper Orthogonal Decomposition (POD) and<br /> Galerkin projection, and we introduce an inner product and formulation<br /> of the equations of motion which enables one to use vector-valued POD<br /> modes for compressible flows. We obtain models between 3 and 20<br /> states, which accurately describe both the short-time and long-time<br /> dynamics. This is a substantial improvement over previous models<br /> based on scalar-valued POD modes,which capture the dynamics for short<br /> time, but deviate for long time.<br /> <br /> | flags = <br /> | tag = rcm01-ceas<br /> | id = 2001e<br /> }}</div>
