Atomization in Gas - Centered Swirl - Coaxial Injectors ( POSTPRINT )
A preliminary study of atomization mechanisms in gas-centered swirl-coaxial injectors for use in rocket engines has been undertaken. Gas-centered swirl-coaxial injectors differ from other injectors in that atomization occurs from a wall-bounded liquid. Few studies of atomization mechanisms in wall-bounded flows exist; some probable atomization processes have been determined, however. These mech...

15 صفحه اولnumerical and experimental analyzes of inner stream and its effect on formation of spray angle at dual-base swirl injector in a liquid engine
the manner of spray the fuel has an important effect on stability and convenient mixture of fuel and oxidizer. swirl injectors because of formation of uniform spray cone and proper distribution of the fuel have been used in many rocket engines at aerospace industries. formation and development of air core in the interior stream of swirl injectors and simulation of them is complicated. double ba...
متن کاملStochastic modeling of atomizing spray in a complex swirl injector using large eddy simulation
Large-eddy simulation of an atomizing spray issuing from a gas-turbine injector is performed. The filtered Navier–Stokes equations with dynamic subgrid scale model are solved on unstructured grids to compute the swirling turbulent flow through complex passages of the injector. The collocated grid, incompressible flow algorithm on arbitrary shaped unstructured grids developed by Mahesh et al. (J...
