TARGETED LEARNING OUTCOMES
Students are able to understand the complex numerical solution algorithms behind the commercial CFD code while they are developing CFD skills by using commercially
available software for research development and design tasks in industry. Students are able to communicate and interpret CFD efficiently/precisely to achieve
meaningful results in complex situations.
Important Information Please Read Before Completing Your Work
All students should submit their work by the date specified using the procedures specified in the Student Handbook. An assessment that has been handed in after this
deadline will be marked initially as if it had been handed in on time but the Board of Examiners will normally apply a lateness penalty.
Your attention is drawn to the Section on Academic Misconduct in the Students Handbook.
All work will be considered as individual unless collaboration is specifically requested in which case this should be explicitly acknowledged by the student within
their submitted material.
Any queries that you may have on the requirements of this assessment should be e-mailed to firstname.lastname@example.org. No queries will be answered after respective submission
You must ensure you retain a copy of your completed work prior to submission.

NUMERICAL CALCULATION IS EXPECTING TO BE PERFORMED USING FINITE CENTRAL DIFFERENCE AND FINITE VOLUME METHODS. THE COMPUTATIONAL SOLUTION IS GOING TO BE COMPARED WITH
COURSEWORK INCLUDES 4 QUESTIONS.
THE FIRST AND SECOND QUESTIONS ARE INVOLVING IN NUMERICAL SCHEME FORWARD AND BACKWARD DIFFERENCE FIRST AND SECOND ORDER APPROXIMATION. THE THIRD QUESTION INVOLVS
CENTRAL DIFFERENCE APPROXIMATION. FORTH QUESTION INVOLVS FINITE VOLUME METHOD.
THIS IS A INDVIDUAL COURSE. STUDENTS ARE EXPECTING TO COMPLETE THE ALL COURSEWORK INDEPENDENTLY AND ACCURATELY. FOR A LATER SUBMISSON A PERCENTAGE OF MARK WILL BE
DEDUCTED. THIS IS FOLLOWED BY UNIVERISYT AND SCHOOL POLICY FOR A LATER SUBMISSION.
1. U(x) = x2 find the first order backward difference approximations to Ux(4) using : a) h =0.01 (h) h = 0.4 (c) h = 0.8
2. U(x) = x2 find the first order forward difference approximations to Ux(2) using : a) h =0.1 (h) h = 0.6 (c) h = 0.36
3. U(x) = x2 using Central difference approximation and show that is (a) first order accurate to Ux(2) (b) second order accurate to UXX(2) while h = 0.04 h = 0.02
and h = 0.03
4. Now discuss a problem that includes sources other than those arising from boundary conditions. Following figure shows a large plate of thickness L = 3 cm with
constant thermal conductivity k = 1 W/mK and uniform heat generation q = 1000 kW/m3. The face A and B are at temperatures of 150 oC and 350 oC respectively. Assuming
that the dimensions in the y and z direction are so large that temperature gradients are significant in the x directions only calculate the steady state
temperature distribution. Compare the numerical result with the analytical solution. The governing equation is: 0=+??????qdxdTkdxd
Surface area of plate is A= 2 m2
Comparison with the analytical solution
The analytical solution to this problem can be obtained by integration twice with respect to x and by subsequent application of the boundary conditions. This gives:
