Extremely difficult to solve and complex which
cannot be solved by hand

Software Revolution
LED TO !!!!

• That uses methods and algorithms to predict
• How the liquids and gases behave ?
• How they work with the product we design ?

In the design world we call this COMPUTATIONAL
FLUID DYNAMICS
5
COMPUTATIONAL FLUID DYNAMICS

• Fluid flow is study of how liquids and gases move
  in and around solid objects.
• Heat transfer is study of how things heat and
  cool and the cause of these temperature changes.
• With CFD we can understand the
• flow and heat transfer throughout
• the design process

6
What can you do with CFD Analysis

• Challenges can be solved before they turn into
  serious problems.

• Evaluate product performance

• Complements actual engineering testing

• Helps understand defects, problems and issues in
  product/process

?

• Enable higher quality product

• Reduces engineering testing costs

• Avoid costly prototype testing .

• Provides comprehensive data not easily
  obtainable from experimental tests.

7
Why should you use CFD analysis?

• Fluid affects the performance of almost every
  device and structure.
• Fluids are always a serious factor
• It takes energy to move a car or to pump water
  through a pipeline.
• By understanding the forces that effects the
  fluid dynamics
• You can make critical design decision that reduce
  energy consumption and improve efficiency.

8
Risk Reduction

• Products vehicles and structures often fail due
  to miscalculations or judgement error of fluid
  behavior.

Malfunction of computer due to over heat.
Car parts fail
Structures collapse in high winds
