Nozzle Sampling Bias

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.

Influence of an ultrasonic nozzle in spray-drying and storage on the properties of blueberry powder and microcapsules.

The Journal of the Science of Food and Agriculture, 2016
BACKGROUND Recently, ultrasonic nozzle technology has been applied in spray-drying because of its numerous advantages, including providing more uniform droplets and reducing damage observed in bioactive compounds.

The Calorimeter Nozzle Programme

38th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2002
When investigating flow phenomena in rocket nozzles, e.g. flow separation and side-load behavior for different nozzle concepts, or when experimentally screening design considerations for advanced nozzle concepts, the initial experimental effort is generally limited to subscale experiments with high quality diagnostics.

Analysis of Plume Infrared Signatures of S-Shaped Nozzle Configurations of Aerial Vehicle

, 2016
The infrared susceptibility of the propulsion system of an aircraft is significantly affected by nozzle shapes and atmospheric conditions. To examine the effects of nozzle shapes and atmospheric conditions, various nozzle shapes were selected by ...

Nozzle Flow Separation

AIAA Journal, 1998
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.

Propellers in Nozzles

Journal of Ship Research, 1957
The paper deals with the vortex system of the "screw + nozzle" propeller. The results obtained from systematic experiments with propellers in nozzles in which the length-diameter ratio of the nozzle, the number of blades, and the blade-area ratio of the propeller have been varied are discussed.

Condensation in Nozzles

Journal of Applied Physics, 1959
The extent of realization of vapor-liquid phase equilibrium in nozzles has been investigated as a function of initial particle size, kinetic parameters, and nozzle dimensions. It has been shown that condensation will occur on already present particles only for very small sizes and/or large nozzles 20–30 in. or more in diameter.

Supersonic Annular Nozzles

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.
