Aerodynamics and Microstructure Study of Diana Submarine Swimsuit

Science and technology can play an important role in achieving better outcomes in sports. In speed sports, aerodynamics is considered to be one of the decisive factors in winning margins. By streamlining the exposed body configuration in the fluid, the aerodynamic resistance can considerably be reduced. In swimming, it is claimed that utilising the full body swimsuit, the performance can be enhanced. However, there is not enough scientific data available in the open literature to support this claim. Moreover, it is not clear how a swimsuit can minimize aero/hydrodynamic drag. Therefore, the main objective of this work is to study the microscopic effect of swimsuit material. The study was conducted experimentally for a range of Reynolds numbers. A specially developed cylindrical methodology was used to quantify the effects of swimsuit materials on aerodynamic properties. A microscopic analysis of swimsuit materials was also undertaken. The findings indicated that the aerodynamic properties are dependent on the swimsuit surface structure
