Fluid Dynamics and Measurement Techniques

This course covers a comprehensive understanding of fluid dynamics and measurement techniques. It starts with the exploration of various techniques used for visualizing fluid flow, including tracer-based and density-based methods. For instance, it explains how tracers like dyes or smoke can help observe the motion of the fluid. The course then delves into the detailed discussion on Schlieren and Shadowgraph techniques, used in wind tunnel testing, and the importance of model design and mounting arrangements. Further, it focuses on the measurement of pressure using mechanical instruments, such as a pitot static tube, and the use of manometers and boundary layer probes in pressure measurement. Lastly, the course discusses the concept of the Rayleigh Pitot tube and its application in drag measurement on cylindrical bodies and other two-dimensional geometries, including the use of mercury manometers in high-speed applications and the measurement of pressure changes in low-speed and high-speed tunnels.
