- Аннотация: In present paper we perform a combined experimental and theoretical study of a Knudsen pump (KP), which uses membranes, active liquid heating/cooling and microgrids, printed with microstereolithography method. Dependence of pressure difference generated by KP on applied temperature difference, number of stages in the device and Knudsen number in the membrane was investigated. Obtained results are shown to be in good accordance with theory. In addition, the convenient geometry of the microstage allowed for a detailed analysis of the coefficient of temperature loss on a membrane as a function of the geometric and physical parameters of the microstage. At the same time, performed experiments revealed that combination of mixed cellulose ester (MCE) membranes and 3D-printed microchannels with liquid heating/cooling may appear to be inefficient due to high ”effective” pore size of MCE membranes and notable temperature loss on membrane sides (compared to external temperature difference of cooler and heater elements).
