Design and optimization of multistaged Tesla valves using response surface methodology

Abstract

This study presents a geometrically parameterized model for the Tesla valve and investigates the factors influencing its flow resistance characteristics. The research demonstrates that increasing the number of internal channels intensifies fluid collisions at intersection points, resulting in heightened pressure losses at bends and intersections in horizontal pipelines. The effectiveness of the modified Tesla valve structure is analyzed using finite element methods. Experimental validation corroborates the research findings. This study not only unveils the intricate mechanisms governing the flow resistance properties of the Tesla valve but also lays a scientific foundation for enhancing its performance. The practical experiments conducted contribute to validating theoretical advancements, underscoring the practical applicability of the research results. Overall, this study deepens the understanding of the complexity of the Tesla valve, providing a scientific basis for its optimization in practical engineering applications.
