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.

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

Jet flow issuing from an axisymmetric pipe-cavity-orifice nozzle
An axisymmetric air jet flow is experimentally investigated under passive flow control. The jet issues from a pipe of the inner diameter and length of 10 mm and 150 mm which is equipped with an axisymmetric cavity at the pipe end.

Transonic Flow Field Analysis of a Minimum Nozzle Length Rocket Engine [PDF]
The aim of this paper is to develop a profile of axisymmetric minimum length nozzle giving a uniform and parallel flow at the exit section. The study is done at high temperature, lower than the dissociation threshold of the molecules.
