Course Description
This is an introductory course on computational methods for fluid dynamics. Following a preface to numerical simulation and a review of the governing equations for mass, momentum, and energy, the structure and mathematical behaviors of partial differential equations (PDE) will be discussed, which are classified as hyperbolic, parabolic, and elliptic types. A discretization scheme to approximate the mathematical models, i.e., the finite-difference method, will be described along with the analyses for the resulting errors and stability; they are followed by the strategies of allocation and transformation of grids. Some typical CFD techniques are then illustrated, in terms of various schemes suited for different categories of PDE's. With sufficient background in the elements, students shall work on real problems by solving the Navier-Stokes equations based on pressure correction approaches. They will have an opportunity to practice coding and simulation for steady/unsteady flow field. Various methods of discretization other than the finite-difference approach, such as finite-volume method and finite-element method, would be briefly described if time is available.
The aim of this course is to help students gain basic knowledge and understanding of the subject of numerical simulation for fluid mechanics.
Course Objective
Derive and Explain Governing Equations: Students will be able to derive the governing equations for mass, momentum, and energy conservation, and explain their physical significance and appropriate boundary conditions
Classify PDEs and Select Numerical Strategies: Students will be able to classify partial differential equations (PDEs) into hyperbolic, parabolic, or elliptic types based on their mathematical behaviors and select the corresponding numerical solution strategies.
Apply Finite-Difference Methods and Analyze Stability: Students will be able to apply the finite-difference method to discretize mathematical models and analyze the associated truncation errors and numerical stability of explicit and implicit approaches.
Develop Computer Codes for Flow Simulation: Students will be able to write computer codes to implement specific CFD techniques (such as Lax-Wendroff or MacCormack methods) to simulate steady and unsteady flow fields.
Solve Navier-Stokes Equations using Pressure Correction: Students will be able to solve the full Navier-Stokes equations by utilizing pressure correction approaches (such as SIMPLE or MAC methods) to address complex fluid dynamics problems.
