The block diagram of the control systems in the proposed BSWT is illustrated in Figure 1. Figure 1: Schematic diagram of the pressure and temperature control systems in the supersonic wind tunnel. Fuzzy logic has been the area of heated debate and much controversy during the last decades. ...
The free-stream disturbance field in a short-duration supersonic wind tunnel is investigated at a nominal Mach number of Ma =2.54. A specially designed constant-temperature anemometer is used to be able to draw a complete fluctuation diagram within one wind tunnel run (testing time: 120ms). ...
FIG. 2 is a diagram illustrating the performance characteristics of a typical steam ejector; FIG. 3 is a semidiagrammatic illustration of a nonreturn, continuous operation, supersonic wind tunnel embodying the present invention; and FIG. 4 is a semidiagrammatic illustration similar to FIG. 3 sho...

Diagram of the propagation of a sonic boom To do this, engineers need to perform a nearfield computational fluid dynamics (CFD) analysis to predict the sounds created by the pressure buildup of the aircraft’s flight. They then need to compare and investigate the propagation, volume, grid ref...
In the current study, a novel method is proposed and evaluated for PIV measurement inside a closed cycle of organic vapor in a closed wind tunnel for both subsonic and supersonic regimes. This method can be used to prepare the experimental results of simple flow to validate the dense gas ...
A constriction in a fluid flow system, such as an airplane's wing or a wind tunnel, causes a decrease in the cross-sectional area through which the fluid can flow. This results in an increase in the velocity of the fluid, as described by the continuity equation. What is the difference ...
i. The experimental investigation was performed in a T-333 wind tunnel whose metrological characteristics are presented in [13]. The model diagram is shown in Fig. i, where 1 is a steel cone with i0 ~ half-angle fastened in a rhomboidal holder with d = 40 mm diameter of the base ...
