ABSTRACT
As a part of the design process, it is essential to predict the aerodynamics of the flow as it moves over a streamlined body. This is executed with the use of wind tunnels of appropriate Mach numbers, with the influence of computational analysis. But it is mandatory to verify the theoretical results to the experimental results carried out in a wind tunnel. Before testing, it is necessary that the flow parameters, namely the velocity distribution, angularity of the flow, turbulence, are evaluated and are within the margins. This is important when we are evaluating the flow in three dimensions. Thus, ensuring the reliability of the experimental 186results. In order to evaluate the truthiness of the flow, a two-hole spherical flow analyzer is being used. The truthiness of two wind tunnels across India is being evaluated by a two-hole spherical flow analyzer. From the experiment, the data map will be plotted for the flow parameters using the yaw head constant and the respective orientations of the two-hole spherical flow analyzer. Their nature is evaluated and the findings are discussed.
