Computational Fluid Dynamics

4.00

Undergraduate

Outline: Many physics laws like laws of motion, mass conservation law, energy conservation law,
when applied to engineering problems, come in form of Partial Differential Equations (PDE).
There are several softwares available for solving PDEs but they all require enough human
intervention to make if necessary to understand background theory. In this course we will learn
about Finite Volume Method (FVM), the most common method of solving PDEs computationally.
Though the course is titled based on Fluid Dynamics but materials discussed here should be
accessible to and useful for any audience who deals with PDE.
Learning objectives:
• Software: OpenFOAM (http://openfoam.org/)
• Physics to PDE: derivation of PDEs
• Finite Volume Method (FVM): PDEs to linear algebraic equations
• Implementations of FVM on OpenFOAM: C++ programming
References:
• The Finite Volume Method in Computational Fluid Dynamics An Advanced Introduction
with OpenFOAM and Matlab by F Moukalled, L Mangani, and M Darwish
• OpenFOAM user and programmer guide
Pedagogy: This course will be problem/project driven. This means that for each learning objectives
we will pose a list of small projects. Using the given references and internet, students will need to
figure out solutions on their own. The instructor will function as mentor and the contact hours will
be spent only on discussion, and not too much instructions.
Prerequisites:
Mathematics : Multi-variable Calculus,
Physics : Newton's laws of motion, work, energy, momentum
Computers : C++
Other courses (helpful but not mandatory):
ODE, PDE, Numerical Analysis, Linear Algebra, Fluid Dynamics
Assessment: Entirely on project reports (written and oral)

Prerequisites: MAT 102 Calculus II or MAT 103 Mathematical Methods I. MAT 230 Ordinary Differential Equations or MAT 104 Mathematical Methods II.
Overview: Many physics principles like conservation of mass, momentum, energy, when applied to real life scenarios, take the form of PDEs. In this course we will learn how basic physics concepts together with simple calculus translate into mathematical models of many engineering problems in the form of PDEs.
