ENP Alger - Learn the Computational Fluid Dynamics with ANSYS Fluent Etablissement

Hourly volume: 50 hours

Objectives

This course aims to introduce learners to the theory and practice of computational fluid dynamics (CFD) using ANSYS Fluent software. By the end of this course, learners will be able to:

1.Understand the fundamental principles of CFD, including governing equations, the Finite Volume Method (FVM), meshing.

2.Develop skills in setting up, solving, and post-processing CFD simulations using ANSYS Fluent software.

3.Apply CFD techniques to solve real-world engineering problems, ranging from simple to complex cases.

At the end of this course, learners will have a strong foundation in computational fluid dynamics principles and practical experience with ANSYS Fluent software. This will enable them to apply CFD techniques to a wide range of engineering problems and pursue more advanced topics in CFD and related fields. Learners will work on a project to apply their knowledge of ANSYS Fluent to a real-world engineering problem.
