Advanced Computational Fluid Dynamics


Overview:

  • Improve your understanding of various aspects of computational fluid dynamics, its limitations and advantages.
  • Become familiar with the transformation of the equations of fluid motion from physical space to computational space and numerical algorithms for the solution of Euler, parabolized Navier-Stokes, and Navier-Stokes equations.
  • Learn the fundamentals of the unstructured grids and finite volume schemes.

Key Topics:

  • Grid-Generation-Structured Grids
  • Transformation of the Equations of Fluid Motion from Physical Space to Computational Space
  • Euler Equations
  • Parabolized Navier-Stokes Equations
  • Navier-Stokes Equations
  • Grid-Generation-Unstructured Grids Incompressible Navier-Stokes Equations
  • Finite Volume Schemes

Who Should Attend:

This course is designed for engineers, scientists, and technical managers who are interested in development and/or implementation of available CFD codes. The aim of this course is to extend the concepts of numerical schemes to a system of equations typically expressed in a vector form. The content of this course is equivalent to a one-semester graduate course. Furthermore, you must have had an introductory course in CFD, e.g., the AIAA Introduction to Computational Fluid Dynamics course. Access to a high-end PC, workstation, or a mainframe computer, along with a FORTRAN compiler and graphics, is necessary for applications.
