Book Description
Computational fluid dynamics (CFD) is a powerful tool that enables engineers and scientists to simulate fluid flows in a variety of applications, including thermal engineering, biomedical engineering, and environmental modeling. This book provides a comprehensive introduction to CFD, encompassing fundamental theory, mathematical and numerical techniques, and practical applications. The book begins by systematically introducing the basic concepts and terminology of CFD, such as the continuity equation, Navier-Stokes equations, energy equation, source/sink terms, and types of grids. The mathematical and numerical methods utilized to solve the CFD governing equations, including the finite difference method and the finite volume method, are then described in a beginner-friendly manner, accompanied by vivid and straightforward graphical illustrations. In addition to covering the foundation of CFD theory, the book presents several practical applications of CFD in diverse fields such as biomedical modeling, renewable energy, and thermal engineering. To extract useful information, the simulated CFD results need to be analyzed and visualized. Therefore, the book demonstrates common post-processing and visualization techniques, such as contour plots, streamlines, vectors, and charts. Overall, this book provides a comprehensive introduction to CFD, encompassing the essential theory, methods, and applications, making it an ideal choice as a textbook for graduate and post-graduate students or a reference for researchers and engineers working on CFD simulations.

Book Description
The present work carries out numerical simulations of viscous incompressible flow past a sphere or a spheroid at low Reynolds numbers. When the flow passes a sphere or a spheroid, the flow will have its motion changed because of the shear stress from the surface of the object. This change of motion also differs at different Reynolds numbers based on the geometry of the sphere or spheroid. Many fluids researchers have conducted experiments to investigate the variations of the flow past a sphere at low Reynolds numbers. But the research on flow past a spheroid mainly focuses on cases at high Reynolds numbers (Re>105). Up to date, numerical study on flow past a spheroid at low and intermediate Reynolds numbers (

Book Description
This book contributes to the fundamental understanding of the physical mechanisms that take place in pseudo turbulent particulate flows. In the present work we have considered the sedimentation of large numbers of spherical rigid particles in an initially quiescent flow field. We have performed direct numerical simulations employing an immersed boundary method for the representation of the fluid-solid interface. The results evidence that depending on the particle settling regime (i.e. Galileo number and particle-to-fluid density ratio) the particles may exhibit strong inhomogeneous spatial distribution. It is found that the particles are preferentially located in regions with downward fluid motion. The particles inside clusters experience larger settling velocities than the average. The flow in all flow cases is observed to exhibit characteristic features of pseudo-turbulence. The particle-induced flow field is further found to be highly anisotropic with dominant vertical components. The results indicate that, in the present flow configurations, the collective and mobility effects play significant role for the particle and fluid motion.

Book Description
This volume contains the proceedings of the 13th AIAA Computational Fluid Dynamics Conference. It addresses numerical procedures for the solution of fluid dynamics and interdisciplinary problems. Technical sessions of the conference focus on design optimization, solution adaptive techniques, convergence acceleration methods, high-resolution schemes, parallel computing as well as improved algorithms for the solution of viscous, inviscid, and multi-component flow applications. The programme also includes a panel discussion addressing the evoluting roles of government, industry and academia in future CFD developments.
