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...
متن کاملEffect of temperature on atomization in gas centered coaxial injection systems
This paper summarizes the current status of research work carried out at IISc on the characterization of liquid sprays developing from gas centered coaxial injection systems. The coaxial system injects an annular swirling liquid sheet and a central gaseous jet. The interaction process between the swirling liquid sheet and the non-swirling gaseous jet results in a fine spray. The present study a...
متن کاملAtomization of Wall - Bounded Two - Phase Flows ( PREPRINT )
The current understanding of droplet generation processes from liquid films is reviewed. Films are defined as liquids with one free and one wall-bound surface. In many of the systems where films occur atomization is an undesirable side-effect of the two-phase flow. The motivation for this study, however, is a process where atomization from the film is the goal—a gas-centered swirl coaxial rocke...
متن کاملCore Length and Spray Width Measurements in Shear Coaxial Rocket Injectors from X-ray Radiography Measurements
Shear coaxial injectors are so named because they rely on the shear between an outer low-density, high-velocity annulus and a high-density, low-velocity inner jet to atomize and mix a liquid and a gas. These sprays have an intact core near the injector and the high amount of light scattering its corrugated surface produces creates large optical densities. These high optical densities, in turn, ...
متن کاملEffect of Novel Swirl Distributor Plate on Hydrodynamics of Fluidized Bed Gasifier
The main advantage of a fluidized bed is its capability in excellent gas-fuel mixing. However, due to the lacks of gas radial momentum, its lateral mixing of gas-solid is not adequate. Therefore, this research is focused on fluidized bed hydrodynamics enhancement using the modified gas distributor plate design. For getting an optimum fluidized bed hydrodynamics prediction, three different class...
