Abstract The non-invasive nature of optical diagnostic techniques is advantageous in studying micronozzles, as it safeguards the undisturbed highly sensitive micro-scale flow field. In this work, a laser-based interferometric Mie scattering system developed using virtually imaged phased array to quantitatively measure one-dimensional velocity profile at exit micronozzles. A narrow-linewidth solid-state laser used light source, acetone-seeded air gas, and estimated from Doppler shift...
The need for compact, fast-response, and real-time sensors detecting toxic gases pollutants has generated interest in mixture separation using micronozzles. current work numerically investigates the aerodynamic process associated with two-dimensional planar curved micronozzles operating under vacuum exit conditions. direct-simulation Monte Carlo (DSMC) method is used to simulate gas mixtures various compositions inlet mole fractions. effect of curvature geometry, differential wall heating,...
A numerical investigation of the aerodynamic separation associated with converging–diverging two-dimensional planar micronozzles is reported. The impact divergent section shapes such as linear, bell, and trumpet, effect different back pressure conditions, flow features are studied. Simulations used direct simulation Monte Carlo method validated available experimental data. lateral found to be influenced by nozzle shape. performance throat sizes indicates dependence exit Kn on performance....
