抄録
In the present paper, the pessure performance of a screw-type viscous micropump is investigated by mean of a experiment, a numerical simulation and a theoretical analysis. The several conditions of Reynolds numbers and numbers of turns of a screw groove, or a screw thread, are examined. In experiments, a centimeter-scale, i.e. not micrometer-scale, pumps are used and the low Reynolds numbers corresponding to micrometer-scale flow are realized by using glycerin as working fluid and rotating the screw at quite low speed. The experimental pressure performance shows straight lines with negative slopes. In the numerical simulations, the continuity equation and the three dimensional Navier-Stokes equations are numerically integrated by using the SIMPLE. The numerical pressure performance shows good agreements with the experimental one with respect to the qualitative and quantitative aspects. In the theoretical analysis, the quite simple formula of the pressure performance is derived from the two-dimensional Navier-Stokes equation in the flow direction based on the analytical integrations by using the low Reynolds number approximation, similarly to the two-dimensional lubrication theory. The theoretical pressure performance shows the adequate agreements with numerical and theoretical ones. Therefore, the formula can be used in the parametric survey in the design process.
