Primary breakup simulation of a liquid jet discharged by a low-pressure compound nozzle
چکیده انگلیسی

The aim of this paper is to demonstrate the capability of a numerical approach to retrieve the involved primary breakup process in the case of a single triple disk compound injector. The present study is based on a coupling between internal flow simulations and DNS of primary breakup. The internal flow is described through RANS and LES simulations and comparisons with experimental data validate the calculation accuracy. DNS of the primary breakup is then presented (coupling level set, VOF, ghost fluid methods) and discussed by comparing the results (morphology, jet angle, perturbation wavelength) with experimental visualizations.


► Study of the primary breakup of a liquid jet discharged from a low pressure nozzle.
► Coupling between internal flow simulations and primary breakup DNS.
► Internal flow simulations carried out with both RANS and LES methodologies.
► DNS primary breakup couples level set, VOF and ghost fluid methods.
► Experimental validations (hot wire anemometry, close-up visualizations).
