Designing and manufacturing the multiple jets simulator and experimental investigation of the multiple jets in crossflow at low velocity ratios have been studied Together with design and build a low-speed wind tunnel. A specific rake is used to determine the flow field pressure and changes in static pressure measured by pressure taps in the near field of the jets. There are generally three regi...

In this study, the missile staging process by implementing a side-injected jet is simulated numerically. The problem is considered to be axisymmetric and the thin shear layer approximation of Navier-Stokes equations along with an algebraic turbulence model is used in a quasi-static form for the calculations. The free stream corresponds to a very high altitude flight condition with a Mach number...

During its near-ground hovering phase a Short Take-Off and Vertical Landing (STOVL) aircraft creates a complex three-dimensional flow field between jet streams, the airframe surface and the ground. A proper understanding and numerical prediction of this flow is important in the design of such aircraft. In this paper an experimental facility, used to gather validation data suitable for testing C...

The development of high-performance thermal systems has increased interest in heat transfer enhancement techniques. The application of additives to heat transfer liquids is one of the noticeable effort to enhance heat transfer. In this paper two-dimensional unsteady incompressible nanofluid flow in a confined jet at the laminar flow regime is numerically investigated. The Mixture model is consi...

To optimize the submerged entry nozzle (SEN) for an ultra-thick slab mold, a mathematical model has been established. The molten steel flow and solidification, inclusion transports, meniscus fluctuation have investigated through model. Compared with concave-bottom SEN cases, convex-bottom decreases imping depth of jet increases horizontal velocity temperature on meniscus. However, remelting sol...

Abstract An improved primary method for the calibration of liquid flow meters based on dynamic weighing has been adopted at Istituto Nazionale di Ricerca Metrologica. Compared to other methods currently in use, submerged jet flows, proposed advantage not requiring correction hydrostatic buoyancy force exerted immersed tube. This is possible since immersion depth tube held constant during proces...

Confined plunging jets are investigated as potential outfalls for the discharge of desalination brine. Compared to offshore submerged that rely on momentum induce mixing, released above water surface utilize both and negative buoyancy. Plunging also introduce air into column, which can reduce possibility hypoxic zones. In contrast unconfined jets, confined include a confining tube, or downcomer...
