DIRECT MODELING FOR COMPUTATIONAL FLUID DYNAMICS

More about the book

Focusing on computational fluid dynamics, this book explores the development of CFD algorithms through direct modeling of flow motion in discretized spaces. It introduces the unified gas-kinetic scheme (UGKS), which effectively captures gas evolution across various flow regimes, from rarefied to continuum. The UGKS offers a continuous spectrum of governing equations, enhancing numerical accuracy and providing a comprehensive understanding of fluid dynamics in diverse scenarios.
