Shannon Entropy Computations in Navier–Stokes Flow Problems Using the Stochastic Finite Volume Method [PDF]

Entropy
The main aim of this study is to achieve the numerical solution for the Navier–Stokes equations for incompressible, non-turbulent, and subsonic fluid flows with some Gaussian physical uncertainties. The higher-order stochastic finite volume method (SFVM),

A New Stochastic Model Updating Method Based on Improved Cross-Model Cross-Mode Technique

Sensors, 2021
This paper proposes a new stochastic model updating method to update structural models based on the improved cross-model cross-mode (ICMCM) technique. This new method combines the stochastic hybrid perturbation-Galerkin method with the ICMCM method to ...
