Final Report Summary - ELBM (Frontiers for multi-scale computational fluid dynamics)
Whether predicting the turbulent motion of boiling water, next week’s weather, or future energy production technologies, the varied consequences of fluid motions on human activity are undeniable, with the role played by predictive computations dramatically increasing.
Our approach to computing fluid flows, the Entropic Lattice Boltzmann Method (ELBM) is inherently physical and deeply rooted in statistical mechanics, with a kinetics framework translated onto a lattice in position, momentum, time and space. It is coupled closely with new computational ideas that enable predictive simulations in extremely complex geometries more efficiently, accurately, and robustly than heretofore possible. We have developed advanced lattice Boltzmann models and computations impacting a wide range of contemporary problems, from understanding physics of water-surface interactions, transition to turbulence over turbine blades, bio-inspired self-propulsion and supersonic shock wave-turbulence interaction. Achievements of ELBM project will ultimately change the perspective on computational fluid dynamics.
