Computational Fluid Dynamics also known as CFD is the set of methodologies that enable a computer to produce a numerical stimulation of fluid flows. The word 'stimulation' indicates the ability of a computer to solve numerically the laws that govern the movement of fluids, in or around a material system, where its geometry is also modeled on the computer…

Extract of sample

It is opposite to an experimental investigation by a material model or prototype of the system, such as an aircraft or car model in a wind tunnel.
The role of CFD in this contemporary technological world is crucial. It assists towards the path of global world of Computer Assisted Engineering or CAE that refers to ensemble of simulation tools that support the work of engineer between the initial design phase and the final definition of manufacturing process. The industrial production process uses various software tools for computerization of whole production cycle. Among those tools, the most important are Computer-Assisted Design (CAD), Computer-Assisted Engineering (CAE), and Computer- Assisted Manufacturing (CAM) software. The virtual prototyping environment is made by these CAD/CAE/CAM software systems. (shown in the following figure). In the chart, we can see the different components of a computer-oriented environment used in industry to create or modify the properties of a product. This product also can be a single component such as a cooling jacket in a car engine. In all steps, the related software tools are used in similar ways. Let us see the phases of virtual protype environment for analysis of internal flow of CFD analysis.
1) Definition Phase: The definition phase is the fi ...

Fluid flow can be observed in the flow of gases in pipes, in the Universe, flow of air around the wings of an aircraft, etc. and flow of liquids in pipes, the ocean, flow of blood in blood vessels, etc. and can be studied under various categories like Aerodynamics and Hydrodynamics. Usually these fluids flow inside or around a solid surface and both exert pressure on each other thus making it…
