Summary
This study introduces a new method to evaluate diving fin performance, addressing a gap in optimal fin selection. The research quantifies fin efficiency using thrust, energy, and mechanical factors in a water tunnel.
Area of Science:
- Biomechanics
- Fluid Dynamics
- Sports Technology
Background:
- Limited research exists on selecting optimal diving fins.
- A standardized methodology for evaluating fin performance is needed.
- Popular commercial diving fins require objective performance analysis.
Purpose of the Study:
- To develop and present a novel methodology for evaluating the dynamic ability and efficiency of diving fins.
- To analyze the performance of two popular types of commercial diving fins.
- To establish a foundation for future analysis of advanced fin designs, such as biomimetic fins.
Main Methods:
- Experiments were conducted in a specialized water tunnel equipped with a measuring system and strain gauges.
- An artificial leg mechanism simulated fin movement, generating movement algorithms.
- Fluid velocity was controlled and measured using a pump and an ultrasonic flow meter.
Main Results:
- The study successfully established a method to quantify fin efficiency.
- Fin efficiency was calculated based on generated thrust, electrical energy consumption, and mechanical efficiency.
- The methodology provides a basis for comparing different fin designs.
Conclusions:
- The developed methodology offers a robust approach to assessing diving fin performance.
- This research addresses the paucity of literature on optimal fin selection.
- The findings pave the way for comparative analysis of new fin technologies, including biomimetic designs.
