Nucleation of copper during supersonic expansion [PDF]

open access: yes, 1989
Nucleation of copper vapor during gas expansion in a supersonic nozzle is investigated. Time scales for nucleation delay and supersaturation doubling are considered in establishing the need for non-steady state nucleation theory. A population balance model is constructed for tracking the size spectrum of stable clusters formed from self nucleation and ...

Numerical investigation of transitional supersonic axisymmetric wakes

open access: yes, 2006
Transitional supersonic axisymmetric wakes are investigated by conducting various numerical experiments. The main objective is to identify hydrodynamic instability mechanisms in the flow at M=2.46 for several Reynolds numbers, and relating these to ...

PENETRATION OF A SHOCK WAVE IN A FULLY SUPERSONIC FLAME FRONT WITH THE FORMATION OF AN EXPANSION FAN [PDF]

open access: yesINCAS Bulletin, 2011
In a previous paper [3] was treated the ,,simple penetration” of an incident shock wavethrough a fully supersonic flame front in the space of the hot burnt gases, situated in a supersonictwo-dimensional flow of an ideal homogeneous /combustible gas was ...

A process-oriented thermodynamic framework for gas–solid equilibrium under alternative expansion constraints in supersonic separation systems

open access: yesChemical Engineering Journal Advances
Carbon capture and storage (CCS) processes are of utmost importance in the hard-to-abate industry sector; therefore, supersonic separators are increasingly investigated as compact process units for gas treatment, where rapid expansion can induce solid ...

Safety and Effectiveness of a High‐Dose, Tailored Tissue Plasminogen Activator Therapy Protocol: A Joint Pediatric Hematology and Cardiac ICU Quality Improvement Initiative Analysis

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric thromboembolism is increasingly encountered in critical care. Systemic thrombolysis with tissue plasminogen activator (tPA) facilitates vessel or valve patency, yet pediatric‐specific protocols remain undefined, and safety concerns persist. Objective To evaluate the efficacy and safety of a tailored, prolonged systemic tPA

Three-dimensional acoustic energy flow from rotating sound sources

open access: yesActa Acustica, 2021
A detailed study of the three-dimensional sound fields around a monopole point source in subsonic and supersonic rotation is investigated. We calculate the sound pressure, the acoustic velocity, as well as the instantaneous and time-averaged acoustic ...
