  04/29/08 There will be no class this Wednesday; the time slot will be used for math exam instead.
  04/25/08 I have posted the solutions for take-home exam; the source codes were also posted on code section of this website.
  04/17/08 We will have a take-home exam next week.
  04/09/08 The second computer project has been posted. In this project, you are asked to use Stream-Vorticity formulation to solve the fluid velocity field. Related sample codes (for cavity driven flow) are available online.
  04/08/08 Solution for the midterm exam is avaliable online.
  03/24/08 I hope you all had a good spring break. Our midterm exam is postponed to this Thursday. The exam will be closed book and note. It starts at 1:00pm in MEEN conference room.
  03/19/08 Happy Spring Break!
The solutions for review problems are posted. As planned, we will have a midterm exam on Tuesday, and I will make myself available to help you on Monday, please stop by my office if you need help. Make sure you understand and are familiar to these review problems.
In the project assignament, the width of the door is 1 meter (this was missing in the orginal sketch).
  03/15/08 To help you prepare for the midterm exam, I posted a list of review problems. These problems are the typical ones you will see in the exam. I will post the solutions later.
  03/14/08 I have posted the codes for solving 2d unsteady heat transfer using various schemes. You may use these codes for the 2nd part of your project where you will have different boundary conditions. For the Crank and ADI schemes, I was not able to cover them in the class; however, I have included them in the lecture notes.
  03/11/08 The first midterm exam will be given on March 25th. It covers the classification of PDEs, FD formulation (Taylor series and polynominal fitting) for derivities in uniform and nonuniform grids, approximating a PDE using various schemes, stability analysis using the von Neumann method, determinating the modified PDE, and iterative solvers(Jacobi, Gauss-Siedel and SOR).
  03/11/08 Homework assignament #5 which is our first project is posted. I made a slight change on the wall boundary condition compared to the one I handed out in the class, so please check the webpage for the latest one. A sample code is also posted which solves a prescribed temperature boundary conditions problem.
  02/28/08 I noticed that some of you fall behind the homework due dates.Please not: March 2nd will be the cut-off date for any late homework.
  02/21/08 Class cancelled due to the conflict with campus job fair. However, the due date for hw#4 remains to be Feb.28.
  02/20/08 Homework #4 is posted. You might want to use the explicit FTCS and implicit Crank-Nicolson codes posted on code section of this website as your starting point.
  02/14/08 Both matlab code and C code for the 1D unsteady conduction problem using Explicit FTCS and Implicit Crank-Nicloson scheme are posted.
  02/12/08 I have posted the MATLAB code for solving the 1D conduction problem with zero flux at the left side boundary, as discussed in the class. Pay attention on how to plot two curves in one figure and how to put legends and labels in MATLAB.
  02/06/08 Homework assignment 3 is out. It's due on 2/19.
  02/06/08 I have posted code for the programming parts of HW#1, it can be downloaded.. Please study the code, compile and run it. After running, you will get two data files under the working directory; using these two data files to draw the graphs as described in hw1(b) and (c). Turn this part of work (mainly the gnuplot plots) on Feb 12 together with HW#2.
  02/05/08 The deadline for turning in Homework Assignment #1 is this Thursday (2/7/08) before the class.
  02/02/08 For those who prefer or are advised by their advisors to program with Matlab instead of C, make sure you familiarize yourself with Matlab. I have ported the C code for 1D heat conduction problem to Matlab (check the Codes page).
  02/01/08 I have put a short review on the basic concepts of fluid dynamics. It can be found in the Lecture Notes page or click here.
  01/28/08 Homework #2 requires you to solve the 1D condcution equation in cylindrical coordinates. The general heat transfer equation in cylindrical coordinates could be found here. However, you need simpfly it to fit the present problem.
  01/25/08 Problems 1, 2(a) and 2(b) in homework #1 is due on Jan. 31. The due date for computer programs will be announced latter.
