Comparisons between the flow structures on leeward of the fence as predicted by CFD models and the wind tunnel measurements were discussed. Velocity values for the two modelling approaches were in good agreement. However, there is a noticeable discrepancy in predicting the turbulence structure.

What is the difference between CFD and wind tunnel experiment?
Once you have the results from a CFD simulation, it is relatively easy to visualize flow features throughout the flow domain and extract plots of flow variables. In contrast, extracting data (other than forces) from a wind tunnel simulation requires a priori (and often expensive) model instrumentation.
What is the role of wind tunnel experiments in CFD validation?
For the design of new aircraft configurations the wind tunnel experiment still represents an indispensable tool in order to predict the aerodynamic performance of single aircraft components as well as the overall configuration and respectively to validate numerical procedures.
What is the purpose of the wind tunnel experiment?
Wind tunnels are large tubes with air moving inside. The tunnels are used to copy the actions of an object in flight. Researchers use wind tunnels to learn more about how an aircraft will fly. NASA uses wind tunnels to test scale models of aircraft and spacecraft.
What is one limitation of a wind tunnel that is used to model the effect wind has on a rocket?
Answer and Explanation:
As space is essentially a vaccum, a wind tunnel cannot be used to model that as wind is only possible when you have atmosphere as a medium.
Combining these complementary disciplines has led to significant improvements in both as well as better understanding of aero- and fluid dynamics. Also, as CFD ...
The CFD code predicted a reasonable air flow rate compared with the wind tunnel result, despite the limitations of the wind tunnel test setup.
