Statistical Analysis of High-Order Moments from Direct Numerical Simulation of a Turbulent Boundary Layer
High-order zero-pressure-gradient turbulent boundary layer statistics are important for turbulence modeling efforts and insight into the nature of turbulent flow. In this thesis, a complete database of third-, fourth-, and fifth-order central velocity moments is presented. The statistics were …

Deep Time: Deep Learning Extensions to Time Series Factor Analysis with Applications to Uncertainty Quantification in Economic and Financial Modeling
… to quantify and explain uncertainty through high-order moments in time series data, along with first principal-based improvements on the standard autoencoder and variational autoencoder. While the first-principal improvements on the standard variational autoencoder provide additional means of …

Coarse-grained models for prediction, uncertainty quantification, and extreme event statistics of turbulent flows in engineering and geophysical settings using physics-consistent data-driven closures
… for the quantification of uncertainty? Can high-order statistics and statistics of extreme events be computed from data-augmented coarse-scale or reduced-order models? These questions are motivated by real-world problems, such as multiphase fluid flows as well as climate modeling. To address …

Mesoscopic Numerical Methods for Reactive Flows: Lattice Boltzmann Method and Beyond
… which tends to plays a significant role if high temperatures (and solid opaque particles) are involved. In the thesis a LBM model for radiation is presented. The scheme is derived from the radiative transfer equation for a participating medium, assuming isotropic scattering and radiative …
