Abstract
This study presents an in-depth investigation of the boundary layer characteristics of air flowing over a flat plate, with a particular emphasis on the transition from laminar to turbulent flow. A detailed experimental analysis was conducted using a wind tunnel, and the results were compared with theoretical models to validate the findings. The experimental setup consisted of a flat plate positioned horizontally in the test section of the wind tunnel. The free-stream velocity was measured using a pitot tube, and the velocity profile was obtained using a hot-wire anemometer. The boundary layer thickness, displacement thickness, momentum thickness, and shape factor were calculated from the experimental data. The results show that the boundary layer thickness increases with distance from the leading edge of the flat plate, while the friction coefficient decreases with increasing velocity. The shape factor remains relatively constant, indicating a consistent boundary layer shape and structure. The velocity profiles exhibit a clear transition from laminar to turbulent flow, with the turbulent boundary layer showing a significant increase in velocity. The theoretical analysis was based on the Blasius solution for laminar flow and the turbulent flow model. The results of the theoretical analysis were compared with the experimental data, and good agreement was found. The study demonstrates the importance of considering both laminar and turbulent flow regimes in the analysis of boundary layer behavior. The findings of this research have significant implications for the design of aerodynamic systems, such as aircraft wings and wind turbines. The results provide valuable insights into the behavior of boundary layers and can be used to optimize the design of these systems for improved performance and efficiency.
