Tell something about differential and integral approach?

1 Answer

Answer :

One may establish a big control volume to encompass the region R and calculate the overall features like drag & lift by studying what happens at the control surface. This procedure is called integral approach. Differential form is needed to analyze the flow pattern and its local interaction with the solid surface. Differential approach aims to calculate the flow at every point in a given flow field in the form P(x,y,z,t).
