I cannot solve Pro. 6.5 in the Book by Patankar,

February 11, 2004, 13:41

I am sorry to bother you all. Now I am reading the book " Numerical heat transfer and fluid flow" by Pro.Patankar, and sovle the problems following chapters. But it's difficulat to discretize it properly, onec I discretize it, it seems there is not enough boundary conditions to complete the " Simple" procedure. your help and advice will be appreciated.

Regards

problem is stated well but it has a twist though. i have solved it earlier. here is a suggation. USE UPWIND SCHEME TO DISCRITIZE CONVECTIVE TERM AT POINT A. This will eliminate your point 1 for which you dont have the data.

Thanks for your advice, I will try it.

Good weekend.

I sovled the problem 6.5 yesterday, using upwind method to avoid bothering the point beyond point 3. And I also lineaized the (uA)u term before the iterations were put into practice.

Thanks

Good Day.
