IntroductionComputational fluid dynamics, usually abbreviated as CFD, is a
branch offluid mechanicsthat usesnumerical methodsand
algorithmsto solve and analyze problems that involvefluid flows.
Computers are used to perform the calculations required to
simulate the interaction of liquids and gases with surfaces defined
byboundary conditions. With high-speedsupercomputers, better
solutions can be achieved. Ongoing research yields software that
improves the accuracy and speed of complex simulation scenarios
such astransonicorturbulentflows. Initial experimental validation
of such software is performed using awind tunnelwith the final
validation coming in full-scale testing, e.g.flight tests.

Some examples are:-
1. aerodynamics of aircraft and vehicles: lift and drag
numerical simulation of an aircraft in German aerospace center(DLR).
2. Hydrodynamics of ships.

3. power plant
A CFD model simulating the flow and pressure in a reactor coolant pump at the Loviisa nuclear
power plant. The effect of modifications was simulated using the model prior to actual work being
carried out.
4. Biomedical engineering
More recently, Computational Fluid Dynamics (CFD) has emerged as a promising tool, which,
alongside experimentation, can yield insights of unprecedented detail into the hemodynamics of
prosthetic heart valves

Set up
Doman(fluid, solid)boundary condition in fluid Doman(inlet,outlet,walls)we are
testing wing in subsonic wind tunnel, so we are putting air speed in inlet is
equal to 0.75 Mach and static pressure in outlet is equal to zero.

Conclusion.Here we are getting very high pressure in engine nacelle and front
edges of the wing and it can affect wing structure and wing skin also.so
we need here batter design salutation who will support wing shape
aerodynamically.
