Tesla valves are widely used in the field of fluid control. To study the hydraulic performance of straight-through Tesla valves in forward and reverse flow, 16 straight-through Tesla valves with diverse blade parameters were designed in this paper, and hydraulic loss tests were carried out in forward and reverse flow under different working conditions. The results show that the hydraulic loss increases with the increasing working flow rate in forward and reverse flow; at the identical flow rate, the reverse loss is higher than the forward loss. Both the hydraulic loss through the valve and the unidirectional conductivity of the valve increase with increasing blade length, pitch, and number of blades, but too long of a length results in weakened unidirectional conductivity. The hydraulic loss increases with the increase of blade angle, and the unidirectional conductivity decreases with the increase of blade angle. When the blades are arranged in perfect symmetry, the hydraulic loss through the valve is maximum, and the valve has the best unidirectional conductivity.
特斯拉阀在流体控制领域有着广泛应用。为研究直通式特斯拉阀在正向和反向流动时的水力性能，本文设计了16个具有不同叶片参数的直通式特斯拉阀，并在不同工况下进行了正向和反向流动的水力损失试验。结果表明，正向和反向流动时水力损失均随工作流量的增加而增大；在相同流量下，反向损失高于正向损失。通过阀门的水力损失和阀门的单向导通性均随叶片长度、节距和叶片数量的增加而增大，但长度过长会导致单向导通性减弱。水力损失随叶片角度的增大而增大，单向导通性随叶片角度的增大而减小。当叶片呈完全对称排列时，通过阀门的水力损失最大，且阀门具有最佳的单向导通性。
