Status and development of the MARA low-energy branch
2018
The MARA Low-Energy Branch is under development at the Accelerator Laboratory of the University of Jyvaskylä. The facility will be employed for laser ionisation and spectroscopy studies and for mass measurements of nuclei close to the proton drip line. This article presents an updated status of the ongoing development of the different parts of this facility, including the buffer gas cell, the ion transport system, the laser system and the detector stations. peerReviewed
Liquid aluminum particle effects on propagation of waves in solid rocket motor internal flow
2007
Aluminum-droplet effects on propagation of acoustic waves in the internal flow of a solid propellant rocket motor are analysed. Changes of the multiphase flow compressibility are calculated by taking into account both the translational and the pulsational motions of the aluminum droplets in consequence of the acoustic waves. Chemical reactions are not included in the analysis to avoid the complications arising from the non-isothermal and non-chemical-uniform combustion of aluminum in the chamber. Some corrections in current metalized propellant rocket instability calculations accounting for the results of the analysis are proposed.
