Mach Disk Shape in Truncated Ideal Contour Nozzles
, 2007 DLR Lampoldshausen carried out cold flow tests to study the flow field in a truncated ideal contour nozzle at low nozzle pressure ratios. A convex shaped Mach disk was found for nozzle pressure ratios less than 10 and a slight concave one for nozzle ...

Jet noise source distribution for coplanar nozzles: experiments and predictions [PDF]
In this paper we study the mechanism of jet noise production in coaxial flows. We shall present various experimental results for isothermal and heated coplanar jet flows of four area ratios (0.81, 2, 3, and 4), operating at different velocity ratios ...

Anaesthesia, 1967 SUMMARY A case is described where a metal nozzle from a lignocaine spray bottle became detached at laryngoscopy, passing unnoticed into the pharynx and oesophagus. It was subsequently recovered at laparotomy from the patient's large bowel where its further progress had been arrested by an obstruction at this site.

A theoretical study of the performance of resistojet nozzles
, 1972 The theoretical development of four computer models of resistojet nozzle performance is reported. Five main energy loss processes are accounted for; these are (i) frozen chemical rate processes, (ii) finite rate vibrational relaxation, (iii) incomplete ...

Interference effect between sonic nozzles
, 1997 Calibration of a large capacity gas flow meter may be accomplished with a sonic nozzle bank as a reference system. For the design of a compact movable prover which is made with many nozzles, the nozzles should be installed as close as possible.
