Computational Fluid Dynamics Applications in Environmental Hydraulics by Paul D. Bates, Stuart N. Lane and Robert I. Ferguson pdf

Computational Fluid Dynamics Applications in Environmental Hydraulics by Paul D. Bates, Stuart N. Lane and Robert I. Ferguson pdf free download. Computational Fluid Dynamics (CFD) was developed over 40 years ago by engineers and mathematicians to solve heat and mass transfer problems in aeronautics, vehicle aerodynamics, chemical engineering, nuclear design and safety, ventilation and industrial design. Whilst the fundamental equations of fluid motion that formed the basis of such codes had been well known since the 19th century, their solution for problems with complex geometry and boundary conditions required the development of efficient numerical solution techniques and the ability to implement these on digital computers.

The development of this technology in the 1950s and 1960s made such research possible, and CFD was one of the first areas to take advantage of the newly emergent field of scientific computing. In the process, it was soon realized that CFD could be an alternative to physical modelling in many areas of fluid dynamics, with its advantages of lower cost and greater flexibility. Computational fluid dynamics is therefore an area of science made possible by, and intrinsically linked to, computing. Its development has paralleled that of computer power and availability, and as we move into an age of cheap, powerful desktop computing it is now possible, with a little knowledge, to run large and complex 3D simulations on an average personal computer. However, most research advances in CFD continue to originate in the aeronautics and industrial design communities as aresult of the significant investment levels available in these areas.

In such applications the boundary conditions, problem geometry and material properties of any solid surfaces (e.g. drag coefficients) are typically known very precisely and the code is applied to a closed system. In such cases it may be possible to characterize the complete set of process mechanisms that exist and also obtain good experimental data for model validation. Major research questions, therefore, concern improvements to the quality of the numerical solution, the scales of flow resolved by the model for fixed computational costs and the representation of sub-grid-scale processes such as turbulence.

Considerable effort is expended on topics such as numerical analysis, turbulence modelling, grid generation and adaptive meshing. Tolerance of solution errors is also low, and such codes are predominantly used in a deterministic fashion as alternatives to laboratory experimentation. This reductionist epistemology serves industrial engineering applications well, and the techniques thus developed have considerable spin-off benefit in other disciplines such as environmental hydraulics.
