SUMMARY
The works allows to studying theoretically (numerical method + solver Fluent) the flow around the profile. Our attention will be principally takes on the description of the parallel and homogeneous flow. In the same context and in the case of the potential flow, we will take the perturbed function f caused by the presence of the profile. The mathematical formulation of the problem gives for different Mach number several forms of differential equations as (linear or non linear). The solution found for each Mach number interval allows a good understanding of the flow behaviors inside the studies field.
