采用计算流体力学（CFD）和激光多普勒测速（LDA）技术对流体相共振（FPR）混合器进行了研究。在FPR混合器中，管道被浸入容器中的液体中。在管外和管内液体上方产生两个气垫。后者定期加压，使中心管和容器中的液体振荡，为混合提供良好的流动条件。从基本的几何形状开始，进一步开发配置并使用CFD进行模拟，以优化混合质量。两个模拟的结果进行了验证LDA。通过对速度、湍动能、混合质量、混合时间和牛顿数的比较，考察了几何形状和振荡频率对混合质量的影响。通过牛顿数将混合器与标准搅拌容器进行比较。结果表明，FPR混合器可以与螺旋桨搅拌器一样有效。
Fluid Phase Resonance (FPR) mixers are investigated by means of Computational Fluid Dynamics (CFD) and Laser Doppler Anemometry (LDA). In FPR mixers, a pipe is immersed centrally into a liquid contained in a vessel. Two air cushions are produced above the liquid outside and inside the pipe. The latter is periodically pressurised so that the liquid in the central pipe and the vessel is oscillating, providing good flow conditions for mixing. Starting with a basic geometry, further configurations are developed and simulated with CFD to optimise the mixing quality. Results for two simulations are validated by LDA. Comparing velocity, turbulent kinetic energy, mixing quality, mixing time, and Newton number, the influence of geometry and oscillation frequency is investigated. The mixers are compared to standard stirred vessels by Newton numbers. It is found that FPR mixers can be as efficient as propeller stirrers.
