An axisymmetric similarity solution for viscous-transonic nozzle flow [PDF]
An axisymmetric viscous-transonic equation is presented. A nozzle-type similarity solution of this equation has been found, which describes the initial stages in the development of shock waves downstream of a converging-diverging nozzle throat. This solution is an extension of a two-dimensional solution found previously (Sichel 1966). By an appropriate

Analysis of a Low-Angle Annular Expander Nozzle
An experimental and numerical analysis of a low-angle annular expander nozzle is presented to observe the variance in shock structure within the flow field. A RANS-based axisymmetric numerical model was used to evaluate flow characteristics and the model

Statistical modelling for prediction of axis-switching in rectangular jets [PDF]
Rectangular nozzles are increasingly used for modern military aircraft propulsion installations, including the roll nozzles on the F-35B vertical/short take-off and landing strike fighter.

Comparison of synthetic jet actuators based on sharp-edged and round-edged nozzles
Axisymmetric synthetic jet actuators based on a loudspeaker and on two types of flanged nozzles were tested and compared experimentally. The first type of the nozzle was a sharp-edged circular hole.

Aerodynamic Design of a Laval Nozzle for Real Gas Using Hodograph Method
We propose an approach for the design of the subsonic part of plane and axisymmetric Laval nozzles for real gases. The proposed approach is based on the hodograph method and allows one to solve the inverse design problem directly.

Fluidic valve for reactor regeneration flow switching [PDF]
An unusual and in many respects advantageous no-moving-part valve is described,developed for switching fluid flows in a through-flow reactor that requires a periodic regeneration by temporary replacement of the process fluid by another, regeneration ...

Effect of Nozzle Exit Geometry on the Development of Turbulent jets
Results are presented for some features of the structure of turbulent free jets issuing from an equilateral triangular nozzle and from a sharp-edged square nozzle with the same cross-sectional area.

Novel Nozzle Shapes for Synthetic Jet Actuators Intended to Enhance Jet Momentum Flux
An axisymmetric synthetic jet actuator based on a loudspeaker and five types of flanged nozzles were experimentally tested and compared. The first (reference) type of nozzle was a common sharp-edged circular hole. The second type had a rounded lip on the
