Procedure:

1. Virtual model
2. The flow region or calculation domain is divided into a large number of finite volumes or cells
3. Partial differential equations are discretized using
a wide range of techniques: finite difference,
 finite volume or finite element
4. Algebraic equations gathered into matrices
which are solved by an iterative procedure
5. Numerical solution gives the values of the
dependent variables at discrete locations
6. Chemical reaction, Multiphase flow,
mixing, phase change, mechanical movement

CFD is a simulation tool, which uses a power computer and applied mathematics to model fluid flow situations.
• In 1928, the application of CFD started in fluid flow
• Daimler Chrysler was the first company to use CFD in Automotive sector.
• Speedo was the first swimwear company to use CFD
• The adoption of CFD technology by food engineers began in the 1990s.

CFD :

Complements actual engineering testing
Reduces engineering testing costs
Provides comprehensive data not easily obtainable from experimental tests.
Reduces the product-to-market time and costs
Helps understand defects, problems and issues in product/process.
