Description
The Cauchy Green strain tensor provides an effective tool for understanding unsteady flows. In
particular, the dominant eigenvalue of this tensor has been seen to be a reliable estimator of the finite
time Lyapunov exponent. We propose a new method for computing the CG strain tensor using a local
quadratic regression LOESS technique. We compare this LOESS method with several classical
methods using closed form flows, noisy flows, and simulated time series. In each case, the CG strain
tensor produced by the LOESS method is remarkably
accurate and robust compared to classical methods.
