Computer simulation
What is computational fluid dynamics?
Computational fluid dynamics (CFD) is a branch of mechanics that uses numerical analysis and data. Structures to analyze and solve problems involving fluid flows in complex scenarios such as transonic or turbulent flows.
Computers are used to perform the calculations necessary to simulate the free stream flow of the fluid and the interaction of the fluid (liquids and gases) with surfaces defined by boundary conditions. With high-speed supercomputers, better solutions can be achieved and are often required to solve the largest and most complex problems.
Why openfoam?
This ‘Free Software’ is distributed under the General Public License (GPL). That means users are free to use, modify, and redistribute the software. You don’t have to pay for an expensive license like common commercial solutions like Ansys Fluent.
However, that doesn’t mean that OpenFOAM isn’t as powerful as other commercial solutions. It also has other advantages such as having a large community that is involved in the development.

External flow
It flows around multiple types of simple or complex bodies. It is normally applied to vehicles, in order to optimize drag losses.
You can analyze how the pressure spreads from the front face, and then the force on it.
Internal flow
Usually applied over pipes, internal flow shows you the pressure loss of a flow.
In other complex bodies such as cyclone filters, the goal is to describe the flow inside and predict the separation of particles. This type of problem has another complexity because it has two flow phases.
Heat Transfer
Fluids undergo convective heat transfer, moving as their density varies with temperature. This phenomenon involves complex flows that are very difficult to understand without simulations or experimentation.
