Introduction to Computational Fluid Dynamics

In This Section

Synopsis:

This introductory course will prepare you for a career in the rapidly expanding field of computational fluid dynamics.

How You Will Benefit From This Course:

  • Learn the terminology used in CFD.
  • Learn and experience how applications of various numerical schemes to scalar model partial differential equations are used to illustrate the different aspects of CFD.
  • Improve your understanding of the limitations and advantages of CFD.
  • Discover why CFD is the tool for fluid flow simulations and prediction that has virtually none of the inherent limitations of other simulation techniques.

 

Key Topics:

  • Classification of Partial Differential Equations (PDEs)
  • Finite-Difference Equations
  • Parabolic Equations
  • Stability Analysis
  • Elliptic Partial Differential Equations
  • Hyperbolic Partial Differential Equations
  • Scalar Representation of the Navier-Stokes Equations
  • Incompressible Navier-Stokes Equations

 

Who Should Attend:

This course is designed for engineers, scientists, and technical managers who are interested in learning the fundamentals and principles of CFD. The objectives of this course are to provide simple, but in-depth explanations of solution schemes. The content of this course is equivalent to one-semester course offered to upper level undergraduates or first year graduate students. Prior introductory courses in fluid mechanics and partial differential equations are also helpful.
