6 FAQs about [Wind power generation supersonic]

Are supersonic/hypersonic wind tunnels affected by upstream flow fluctuations?

Thus, supersonic/hypersonic wind tunnels and shock tunnels (see Chap. 6) are affected by high levels of upstream flow fluctuations, typically one or two orders of magnitude higher than the real flight cases.

What is a transonic/supersonic wind tunnel?

In transonic/supersonic wind tunnels, the compressed air is desiccated (dried) before storage in the tanks. In high supersonic wind tunnels, it is also necessary to heat the air due to the cooling produced by the adiabatic expansion in the nozzle in order to avoid liquefaction.

Why does a supersonic wind tunnel need to be heated?

In high supersonic wind tunnels, it is also necessary to heat the air due to the cooling produced by the adiabatic expansion in the nozzle in order to avoid liquefaction. To obtain a uniform flow in the test section at the nozzle exit, it is necessary to give the contour of the nozzle a particular shape ensuring a progressive supersonic expansion.

How does the s8ch supersonic wind tunnel work?

The S8Ch supersonic wind tunnel at ONERA, Meudon is equipped with two test sections with identical characteristics and utilises the same power supply and common auxiliaries. Of an open circuit type, the wind tunnel operates continuously at atmospheric conditions at the intake and a downstream suction generated by two 132 kW pumps.

What are the sources of environmental disturbance in a supersonic wind tunnel?

Figure 5.21 illustrates the sources of environmental disturbance in a supersonic or hypersonic wind tunnel. Upstream of the nozzle throat, the heaters, corners, diffusers, compressors, filters, are the source of disturbances in the form of entropy spots of thermal origin or freestream disturbance which constitutes of vortices and acoustic waves.

Why do supersonic wind tunnels need a dryer?

This results in a perturbation of the flow from the transonic regime which requires equipping the supersonic wind tunnels with a dryer in order to eliminate humidity from the ambient air. In transonic/supersonic wind tunnels, the compressed air is desiccated (dried) before storage in the tanks.
