特斯拉阀性能的仿真研究

Simulating the performance of Tesla valve

通过CAD软件建立几何模型,通过COMSOL软件建立数值模型并求解,与实验结果进行对比,并通过数值模拟讨论相关参量对阀门单向流通性的影响.研究结果表明:特斯拉阀门适用于低粘度高密度流体;本文所设计的特斯拉阀门在四阀门情况下dedicatee数能达到3.414;单阀门特斯拉阀的性能相较于多阀门更佳.

A geometric model was established by CAD software in the calculation,a numerical model was established and solved by COMSOL software and compared with the experimental results.The influence of related parameters on the unidirectional flowability of the Tesla valve was discussed through numerical simulation.The research results showed that the Tesla valve was suitable for low viscosity and high-density fluids.The Tesla valve designed in this paper could reach a diodicity number of 3.414 in the case of four valves.The performance of single-valve Tesla valve was better than that of multiple valves.
