Abstract
Abstract
With the recent advancements in manufacturing technologies, researchers have become more optimistic about the fabrication of micro and nano-fluidic devices, which was otherwise far from consideration one or two decades ago. As a result, there has been increased research activity recently in the novel fluidic designs at the micro and nano level. Various Magnetorheological (MR) micropump designs have been proposed and studied in the literature. However, there was no holistic look at these designs in terms of performance evaluations. In this study, we evaluated the performance characteristics of five different MR micropump designs. Two of these designs were our proposed designs, while others were from the existing micropump designs in the literature. Comparisons have been performed based on physics-based simulations, and the highly coupled magneto-solid-fluid interaction simulations were carried out in COMSOL Multiphysics software. For a fair and meaningful comparison, both the material and geometric properties were kept the same, and the simulations were run for one complete pumping cycle. The results showed that the proposed flap valve model and duckbill valve model could pump 1.09 µl and 1.16 µl respectively in 1 sec of pumping, which is more than each of the three existing micropump models. Among the existing micropump models, the behrooz model can transfer up to 1.03 µl of fluid in 1 sec. Moreover, at 0.5 sec, when the magnetic flux density is maximum, the flap valve model and duckbill valve model can pump almost twice as fluid as the ehsani valve model. The results also demonstrate that the flap valve and duckbill valve models are nearly five times faster than the ehsani and xufeng models. Thus, the proposed two micropump models can propel more net volume of fluid than the existing micropump designs, experience low leakage during the contraction and expansion phase, and have faster response times. We believe that the proposed study provides valuable insights for future micropump designs, which have an extensive range of application areas, ranging from insulin dosing systems for T1D patients to artificial organs to transport blood and from organ-on-chip applications to micro-cooling systems.
