The sampling head 12 is thus movable from the position shown, where it is free of interference from the flow over the airframe, to within the aircraft cabin, e.g. for changing the filter. The flow through the apparatus is monitored by a pitot in the pipe 16, connected to a pressure ...
which is positioned in the corresponding outer pipe, of each inner pipe is bent; a bent section is parallelwith the axial direction of the outer pipe; a constant-speed sampling head is arranged at an end; and one end, which is positioned outside the corresponding outer pipe, of each inner...
samplingwetsteamflowsimulation.A mathematical model for predicting the behavior of wet steam flow in the vicinity of the intake head of the sampling probe is presented. The vapor flow field and droplet trajectory in the calculated region have been obtained. The errors caused by non-isokinetic sampl...
