design, analysis and optimization of the ejector injection nozzle supersonic wind tunnel
in this article, an algorithm for designing of a supersonic wind tunnel injection nozzle ejector is presented and based on this algorithm, a new ejector is designed for a supersonic wind tunnel. the injection nozzle consists of a volute, a nozzle, and several vanes. designed injection nozzle is simulated numerically, and the results are compared with the present injection nozzle. the results sh...
متن کاملSupersonic Blowdown Wind Tunnel Control Using LabVIEW
A computer-based, proportional-integral control system for supersonic blowdown wind tunnels was developed in a LabVIEW environment. The control algorithm is based on numerically integrating the differential equations used to model a supersonic blowdown wind tunnel in which the proportional and integral control terms were added and tuned in a simulation to determine their appropriate values. Val...
متن کاملSupersonic Wind - Tunnel Flutter Tests of Two Rectangular Wings
Two rectangular wings of aspect ratio 4 were flutter tested in a supersonic wind tunnel at Mach numbers 1·6 and 2·0 using a technique in which a structural stiffness was varied to give flutter at the Mach number. The results are in reasonable agreement with calculations using theoretical three-dimensional derivatives and arbitrary wing modes, though in general the calculated critical stiffnesse...
متن کاملInfluence of nozzle type, nozzle arrangement and side wind speed on spray drift as measured in a wind tunnel
Spray drift is a great concern because of environmental consequences of agricultural practices. Many studies were conducted in wind tunnel (Miller, 2011; Nuyttens, 2007; Herbst, 2003) mainly focusing on the definition of quantitative deposition on collectors at different distances or heights according to (ISO 22856, 2008). In most cases, only one nozzle positioned frontally (wind direction perp...
متن کاملA Low Cost Numerical Simulation of a Supersonic Wind-tunnel Design
In the present paper, a supersonic wind-tunnel is designed to maintain a flow with Mach number of 3 in a 30cm×30cm test section. An in-house CFD code is developed using the Roe scheme to simulate flow-field and detect location of normal shock in the supersonic wind-tunnel. In the Roe scheme, flow conditions at inner and outer sides of cell faces are determined using an upwind biased algorithm. ...
