A mathematical model is proposed to describe the sampling bias in anisokinetic sampling of aerosols. The nozzle sampling bias is described as a function of the particle's free stream inertial parameter, P, and the particle's free stream Reynolds number, Re0, and the suction ratio, w0, of the sampling nozzle.

During the sea-level ignition process of rocket motors, the nozzle is subjected to an overexpanded e ow condition that can cause high side loads. Prediction of the symmetrical separation location is the e rst key step to a determination of the range of possible side-load magnitudes.

Model tests with nozzles and steering nozzles for trawlers1
International Shipbuilding Progress, 1965With a trawler model several nozzle propeller arrangements were tested in still water both free running and when trawling. Special attention was paid to turning ability and rudder head torques to be expected with steering nozzles.

An analytical method is presented for the design of axisymmetric annular nozzles to yield uniform and axial flow. Computed results are used to display typical matched inner and outer contours, the effects of major initial flow variables, and the resulting wall forces.

Condensation phenomena in nozzles
Heterogeneous Combustion Conference, 1963Abstract The current status of knowledge on condensation phenomena in supersonic nozzles is reviewed for readers primarily concerned with combustion processes. The history and different experimental approaches to the problem are discussed and areas of current applications are pointed out.
