● What is CFD?
• Four science paradigms
• How CFD tasks are defined?
● A CFD Application at design stage
● Future simulation trends for energy industry

6. CFD software as modern oracles
In ancient times oracles were consulted on the matters of
importance, as being best fitted by age, experience or
connections.
Ref: https://www.slideserve.com/JasminFlorian/presentation_32729

7. What a CFD software
package provides?
Brian Spalding says that
‘The user have supplied the ‘if’; then the software package
pronounces upon the 'what will happen ?' just as did ancient
oracles.’
Ref: https://www.slideserve.com/JasminFlorian/presentation_32729

8. Consult a modern oracle
Brian says software packages have become consulting
oracles.
Two things the modern oracles share with the ancient
ones:
1. They cost money ( sheep, oxen or other currency)
2. Their pronouncements are never 100 % reliable.
