Estimation of Flow Field in Natural Convection with Density Stratification by Local Ensemble Transform Kalman Filter

Estimation of Flow Field in Natural Convection with Density Stratification by Local Ensemble Transform Kalman Filter

For estimating thermal flow in a nuclear reactor during an accident accurately, it is important to improve the accuracy of computational fluid dynamics simulations. The temperature and flow velocity are not homogeneous and have large variations in a reactor containment vessel because of its very lar...
