The effect of laser radiation on fluxes of resonance molecules through capillaries in the transition flow regions
Abstract
The flow of SF6 and C2H4F2 through nickel capillaries irradiated by a CO2 laser is investigated experimentally in order to determine the limit of the resonance effect of radiation on molecular fluxes at high gas pressures at the capillary inlet and to investigate transition flow regions. As in the case of Knudsen flows, laser radiation produces a sharp decrease in resonance gas flow; when the radiation is turned off the flow is recovered. The relative reduction of flow becomes more pronounced with increasing inlet gas pressure.
