Summary

A flow control device based on cam actuated valves is designed and implemented on the PM II AMR test apparatus. The objective is to overcome the brief low field period of the nested concentric Halbach array by decreasing the fluid blow width; displacing fluid only when the magnetic field is close to the minimum and maximum values. Flow waveforms are simulated to evaluate varying blow durations with the same displaced volume. AMR experiments are performed which demonstrate an 11.7% increase in exergetic cooling power with a blow fraction of 59%.
