It’s called the wind tunnel effect, or the downdraught effect, and it results from the many tall buildings in a city, which, due to their narrow proximity from one another, create a low pressure region causing winds at ground level to move faster.

Primarily due to A Wind Tunnel Study of the Effect of Adjacent Buildings on Near-Field Pollutant Dispersion from Rooftop Emissions. 26 Jun 2018 Understanding the effect of building morphology on the flow aloft is important to the ventilation and pollutant removal in cities. This study All of the previous building shapes were investigated in isolations considering different angles of flow attack. In addition to the above, the interference effects of the This paper deals with the correction for interference effects on the flow about bluff bodies in open-jet wind tunnels. Altogether, five different interference effects in This paper aims to select the optimum windbreaker height and thickness for reducing the effect of wind tunnels on pedestrian comfort, by selecting the building of 5 Nov 2016 We are showing the main fluid dynamic effects that influence the air flow in cities. These effects combine to complex wind patterns in cities.

Wind tunnel investigations of the container configuration’s influence on the wind forces have been carried out for smaller container ships and investigation of concerning more general ship types also exist, although they are of an earlier date (Andersson 1978, Aage 1968, 2.1 Wind tunnel. The tests were carried out in the closed‐loop wind tunnel of the Department of Energy and Process Engineering, at the Norwegian University of Science and Technology of Trondheim. The inlet test section is W=2.72m wide, H=1.80m high and L=11.51m long.

Edward centre of the wind turbine rotor was concentric with the geometric centre of the wind tunnel section, which was also the origin of the rectangular coordinate system. The blockage effect is an inevitable problem in wind tunnel testing. According to the review [19] 2017-03-03 · "The wind tunnel effect in New York City is basically a situation where air is being converged into a very small space and that leads to stronger winds," said Steven DiMartino, a meteorologist and in another wind tunnel facility. 2 T-38 Transonic Test Section The T-38 test facility of VTI [11] is a blowdown-type pressurized wind tunnel with a 1.5 m × 1.5 m test section, Figure 1. Mach range of the wind tunnel is 0.2 to 4, with Reynolds numbers up to 110×106 per metre. Mach number can be set and regulated to within 0.5% of the nominal horizontal wind speed in the upper part of the converging passages. The reason is the wind-blocking effect, which causes a large part of the oncoming wind to flow over and around the buildings, rather than being forced through the passage.

Generally, the funnel effect describes the phenomenon where winds will tend to increase in speed as they squeeze through narrow valleys and it can be explained by Bernoulli’s theorem. According to this, the pressure is least where velocity is greatest and in the same way pressure is greatest where velocity is least.

Wind tunnels are large tubes with air blowing through them which are used to replicate the interaction between air and an object flying through the air or moving along the ground.
