hi iam interested in cfd so plese send me the basics of these questions as soon as possble by one day so kind of u

1- Why is the need to apply CFD? 2- What are the major advantages and disadvantages of using CFD? 3- What is modelling a physical process means? Why is it essential? 4- What are these items mean in terms of CFD: Discritization, Numerical Grid, Initial Conditions, Boundary Conditions, Sweep, Convergence and Turbulence Modelling.

PART II The overhead projector shown in Figure (1) was found to have an overheating problem of its glass flatbed due to prolonged use. As a computational fluid dynamist, you were asked to study the problem, simulate it and suggest solutions. Figure (1) Simulate the system on the Phoenics CFD Package and present your results in a report format. Make all the necessary assumptions.

Why don't you do your homework yourself ? Do it, or don't do it. But don't ask other people to do it for you.

that would work too!

How about intermittent duty cycle. You know, turn off the projector before the lens cracks. Let cool. Then turn on.

if you have already done it, why do you waste others time reading your posts. Clearly your post seems like you are a lazy student who just want to take short cut. (we are just bored of these types of questions cropping up time and again).
