Modeling of the Interaction of a Side Jet with a Rarefied Atmosphere
نویسندگان
چکیده
The interaction of a jet from a 3000-N-class thruster positioned on the side of a small rocket, with the rare ed atmosphere at 100 and 80 km, is studied numerically. The direct simulation Monte Carlo method was applied to model the three-dimensional jet-atmosphere interaction. Chemical reactions between freestream and plume species were included in the simulations. A two-stage numerical strategy was used, with sequential computations of an axisymmetric plume core ow and three-dimensional plume-freestream interaction. The impact of altitude, angle of attack, rocket velocity, and thrust on ow elds and surface mass uxes is examined.

Modeling of Chemically Reacting Flows from a Side Jet at High Altitudes
The interaction of a jet from a 60-lbf (267-N) thruster positioned on the side of a small rocket, with the rarefied atmosphere between altitudes of 80 to 160 km, is studied numerically. A multistep approach is employed, which combines the successive computation of the flow inside the thruster using a Navier–Stokes solver, the axisymmetric plume core flow, and chemically reacting three-dimension...
متن کاملQuasi-Static Numerical Simulation of Missile Staging
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...
متن کاملThree-dimensional numerical modeling of score hole in rectangular side weir with finite volume method
Local scouring in the downstream of hydraulic structures is one of the important issues in river and hydraulic engineering, which involves a lot of costs every year, so the prediction of the rate of scour is important in hydraulic design. Side weirs are the most important of hydraulic structures that are used in passing flow. This study investigate the scouring due to falling jet from side weir...

متن کاملDesign and Manufacturing of Jet to free Stream Simulator to Experimental Study of Interaction of Oblique Jet in Crossflow
The study of interactions of jet into cross flow at different longitudinal and transverse angles of jet was studied. The following components were designed and constructed: a low velocity wind tunnel to produce the uniform flow, a flat plate with a traverse injection system to simulate the jet injection, and a spatial rake to measure the total pressure. The tests were carried out at longitudina...
