Book excerpt: A viscous pump design is developed and investigated which is more efficient than a viscous pump previously introduced (Etsion and Yaier, 1988). The key to the new design is straight lobes (V-lobes) as opposed to the semicircular lobes of the previous design. The straight lobe analysis, unlike the semicircular lobe analysis, does not produce a closed form solution. Approximations are made that are verified using shape factors and finite element models. Based on the analyses, the lobe geometry for each lobe design is optimized to produce maximum pumping capacity. The results of the analyses and optimizations, which are based on ideal boundary conditions, show that the straight lobe pump is theoretically superior to the semicircular lobe pump. A test rig was devised to test the semicircular lobe and the V-lobe design using a real time data acquisition system. The results of the experiments prove that the V-lobe is superior to the semicircular lobe. The experimental results showed good agreement with the analytical predictions, though some deviations were experienced at relatively low flow rates and high pressures. The deviations were attributed to the fact that the test pump did not have the ideal boundary conditions on which the analysis and optimization were based. Alternate boundary conditions were investigated using finite element models which better described the boundary conditions in the test pump. The analysis based on the new boundary conditions more appropriate to the test pump show excellent agreement with the experimental results.

This book was released on 2018 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Impedance pumps work on a principle that does not require valves to transfer fluid. Perturbing an elastic material fixed with inelastic ends, propagates a unidirectional wave causing fluid displacement. This method of pumping is useful in various biomedical and engineering applications, such as pumping of sensitive bio-fluids (e.g. blood), micro displacement pumps and many more. This experimental research investigation quantifies the increase in net positive displacement of fluid inside a closed loop compliant micro-structured tubing subject to periodic perturbations by varying the wall cross sectional geometry of an elastic test specimen. Five various set of asymmetric walls test specimens were designed, fabricated, and net pumping performance was quantified. Comparisons were made with the baseline having symmetric cross sectional area. It was hypothesized that perturbing thinner wall of an asymmetric tube, with a thicker boundary opposing it, contributes a higher net positive fluid displacement inside a closed loop. Experimental results obtained when compared to baseline were unexpected. The root cause was investigated, by capturing test specimen images using a high speed camera. It was discovered that the design of the test specimen must take in account the modulus of elasticity when selecting material. A video-graphic comparison was made between the fabricated test specimen made of TangoPlus FLX930 in this study and a commercially available hyper elastic material known as latex. Some external changes based on a hypothesis that adding rigid body in contact with thicker wall opposing perturbations should increase fluid flow, were made with the asymmetric test specimens and a solid bar was placed in contact with the thicker boundary wall against the probe perturbations, in attempt to keep the specimen in the desired geometry, and a significant improvement in average flowrate for various frequency was measured in subsequent analysis. This study concluded, that the creation of an efficient miniature pump is conceivable by making certain changes in design and material considerations to the test specimen. Experimental and high speed imaging data from this experiment may be useful to mimic the flows better and efficient at micro level.
