A secondary flow approach to the inlet vortex flow field
… study is presented of the fluid mechanics of the inlet vortex (or ground vortex) phenomenon. The vorticity field associated with the vortex is investigated using a secondary flow approach. In this approach the flow is assumed to be composed of an irrotational primary flow and a weak shear flow, …

Design, Synthesis, and Characterization of Magnetite Clusters using a Multi Inlet Vortex Mixer
… colloidally stable magnetite clusters. A Multi Inlet Vortex mixer (MIVM) was used because it is a continuous process that yields particles with relatively narrow and controlled size distributions. In the MIVM, four liquid streams collide under turbulent conditions in the mixing chamber where …

Vortex control of two-phase refrigerant flow in nozzles and its application in ejector vapor compression cycles
Vortex control is a novel two-phase convergent-divergent nozzle restrictiveness control mechanism which achieves flow control by adjustable nozzle inlet vortex strength. The nozzle can become more restrictive with increasing inlet vortex strength. Vortex control can potentially provide flow control …

Characterization and Pharmacokinetics of Rifampicin Laden Carboxymethylcellulose Acetate Butyrate Particles
… two different formulation techniques. Multi inlet vortex mixer (MIVM) and manual spray drying techniques were used to form the rifampicin containing CMCAB particles. Characterization studies and analyses of particles revealed differences in particle sizes, shapes and drug loading between the …

Flow study of the nozzle region of the space shuttle solid rocket motor
… and recirculation flows around the nozzle. Vortex formation near the nozzle inlet was also observed and was the prime focus of this investigation. Because the nozzle inlet geometry was very similar to an aircraft engine inlet operating close to the ground, vortices seen in this investigation …

Effects of axial turbine tip shroud cavity flow on performance and durability
… at cavity exit. One of the vortices, the cavity inlet toroidal vortex, sets the loss level within the cavity inlet and the mass ow recirculated out of the cavity into the main flow path. It is found that tip shroud cavity flow incurs a 0:85% debit in stage eciency per 1% of main flow fluid …

Synthesis, Characterization and Structure-Property Relationships of Polymer-Stabilized Nanoparticles Containing Imaging and Therapeutic Agents
… rapid precipitation technique using a multi-inlet vortex mixer. Quantitative control over iron oxide loading, up to 40 wt%, was achieved. Correlations between particle parameters and transverse relaxivities were studied within the framework of the analytical models of transverse relaxivity. …

Numerical and experimental investigation of VG flow control for a low-boom inlet
The application of vortex generators (VGs) for shock/boundary layer interaction flow control in a novel external compression, axisymmetric, low-boom concept inlet was studied using numerical and experimental methods. The low-boom inlet design features a zero-angle cowl and relaxed isentropic …
