CFD test.
Hello everyone.

Tomorrow I will be sitting an open-book CFD test which I can bring the paper back to my house. So I am looking forward to get massive guidance from you all to help me answering the questions next morning.

Thank you :)

whats the name of the class? topic? CFD is such a wide area, from application to theoretical mathematics...

afadzlan November 14, 2011 09:08 Here is the test I had mentioned yesterday.
Neglect all the part A questions because I think the answers might be in the text book.

So I am asking your help to do part B. Assume/treat me as a person who is totally knoob and knows nothing even the first law of thermodynamics.

Thank you.
Oh yes, the submission date is by this Wednesday. Help me real quick guys :D

hm, what exactly do you need help with? it seems like you have a matlab program at hand to plot the solution?!? or are you supposed to write the program? it's not clear from the description....

never mind sir, after 2 hours of studying the finite volume method, i have realized that question is so easy.

I have solved it just in 1 hour.

By the way, the question asks us to determine temperature profile using finite volume method. I used 5 nodes with equal characteristic lengths (dx) to make discretized equation, ap= aw+ae+su in order to govern temperature equation of each node. Sound familiar?

After obtaining all the temperature values, we can plot the profile using Mathlab; y-axis is for temperature and x-axis is for dx.

Thank you anyway for your concern sir. :)

I am from Malaysia, thats why my English sucks :o
