Dear friends,

I dint get opportunity to study much. I joined in a job at very early stage. I even dont know calculus. Now i am trying to learn about fluid mechanics and CFD. I am having some really basic doubts. Please bear with me.

1) What is difference between Bernoulli and Euler equation.
2) What is Navier Stokes equation? (In layman terms)
3) Poisson equation.
4) Ludwig prandtl equation.
5) In CFD what does convergence mean. Initial conditions are same, equations are same and model, boundary conditions all are the same. But why there is a variation in result and finally why it will converge?

Please if any one can explain this in layman terms, i can appreciate it better.
