On the prediction of ultimate separation in parametric pumps

摘要: Quantitative theories based on first principles are derived to explain the roles of heat and mass transfer in attainment steady state or ultimate separation closed direct-thermal-mode parametric pumps. The theoretical results agreement with applicable experimental data, including anomaly called reversed separation. Under conditions when axial dispersion is much greater than molecular diffusion, theory predicts experiments confirm that 1/ln(α∞) varies a linear way fluid displacement at constant frequency. An additional asymptotic result suggests Sh » PeM, there simple connection between PeM which supported by data.
