A polytropic analytical equation system for the internal e ow of nozzles and ducts has been developed by a solution to the combined friction/area change compressible e ow equations. Validation of the system is sought through comparison with experimental data and numerical simulations using FLUENT in the prediction of the performances of two ...

Journal of Spacecraft and Rockets, 1971
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.

The Effect of Nozzles and Nozzle Loadings on Shell Buckling
Volume 3: Design and Analysis, 2015This paper investigates the effect of nozzles and nozzle loadings on the overall buckling capacity of a vessel subject to external pressure designed to ASME VIII Div 1. ASME VIII Div 1 provides a well-established design-by-rule (DBR) approach for vessels subject to external pressure, but this takes no consideration for the presence of ...

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.

Truncated Perfect Nozzles in Optimum Nozzle Design
ARS Journal, 1961A graphical technique for selecting optimum nozzle contours from a family of truncated perfect nozzles is presented which permits simultaneous consideration of various types of optima. This procedure includes the effects of friction, as well as the thermodynamic properties of the reacting gas.

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.

American Industrial Hygiene Association Journal, 1975
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.

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.
