What Is Computational Fluid Dynamics – CFD?

Computational Fluid Dynamics (CFD) is the branch of CAE that simulates fluid motion and heat transfer using numerical approaches. 

CFD acts as a virtual fluid dynamics simulator. You can visit to get information about the CFD simulation of the pump suction chamber.

CFD is a set of computational simulation techniques, used to obtain and interpret computational solutions for the conservation equations for physical quantities of interest in a flow, which are:

  1. Mass conservation
  2. Momentum and energy conservation

These simulation techniques predict physical and/or chemical phenomena occurring in inflows. They will simulate the physical phenomena in an approximate way to the differential equations. Those differences refer to errors or residuals. 

To solve problems in CFD, it’s necessary to specify the problem, i.e. its geometry, flow conditions, and the requirements for simulation (precision level, require time, solution of the interest parameters).

In CFD it’s possible to model and evaluate the fluid flow performance in our study model. The application of CFD simulation offers a set of advantages when compared to theoretical and experimental studies:

  1. Purchase and operation low cost
  2. Detailed information about the fluid flow studied
  3. Allows the quick change of parameters in the flow analysis

Despite all, the CFD does not substitute theory and experience; we should always approach two, to interpret the results. The comparison with experience gives us the accuracy achieved by the simulation.
