Gourd-shaped wind tunnel a little like north and south, looking across the middle narrow, such as arches, front and rear are open, such as the Office of breeze.
Therefore the flow velocity profile for the underbody of a real Shinkansen train was reproduced in wind tunnel tests and a method was developed to perform a quantitative analysis of the aerodynamic noise produced in the bogie area.
He conducted studies on the size and shape distributions of raindrops and constructed a novel wind tunnel in which water droplets of various sizes could be held stationary for a few seconds.
This wind tunnel is an extremely important part of Japan's aviation history, used in the design of aircraft such as the KOKENKI long-range research aircraft, which broke the world record for long-distance flight, and the YS-11 domestic passenger airplane.
In addition to the wind tunnel testing, ATS wanted to perform a CFD analysis. In order to perform this analysis, 3D Scan IT prepared a surfaced model(NURBS model) using the PolyWorks IMEdit™ module.
The wind tunnel has a diameter of 4.5m and a height of 19.8m in the center where the wind is re-circulated in the cylinders on the left and right to create wind power from the gentlest of breezes to that far exceeding the most furious typhoon you have ever seen.
Excellent aerodynamic performance of the NSX exterior was achieved through numerous tests conducted at advanced wind tunnel facilities in Ohio and Tochigi.- Interior emphasizes visibility and comfortUnder the concept of"human-support cockpit," the interior was designed to allow the driver to focus on driving.
A wind tunnel test using a model showed that wind resistance was reduced by 10 percent.1 Applying this percentage to a 180,000 DWT bulk carrier, a reduction in CO2 emissions of 520 tons a year can be realized as a result of the enhanced fuel efficiency.
The results of the wind tunnel test and the mock-up test in Shimamaki showed that, when wind direction is perpendicular to a vehicle, the lateral force coefficient that greatly affects vehicle overturning is smaller in fluctuating winds than in uniform flow Fig.4.
The stakeholders responsible for some of the fastest cars in the world are considering a move that would prohibit wind tunnel testing, but their proposal has been met with resistance from team leaders and fans alike, who don't think CFD technology is mature enough to obviate real-world wind tunnel testing just yet.
We also chose to use a 50% model rather than a 60% model and we chose to run that model quite a long way forward in the wind tunnel, so this gave us the opportunity to best inspect the wake of the car.
This wind tunnel aims at contribution towards various researches into the following subjects: disaster prevention of strong wind and flutter, aerodynamics of bluff bodies, behavior of the atmospheric boundary layer, prediction of wind systems, and utilization of wind energy.
For the tests, researchers installed an aircraft motor system designed by JAXA in a 6.5-m x 5.5-m low-speed wind tunnel and measured motor shaft power, motor efficiency, propeller thrust, the temperatures of various motor system parts, and other values.
Brüel& Kjær can read the Exa model results in the NVH simulator and this allows customers to hear wind tunnel noise and simulation changes in context, with all the other sources of car noise, including the engine, road noise, intake and exhaust.
ATS wanted to test the boattail performance in a wind tunnel.“The goal was to create a file that we could use in a rapid prototyping process to quickly create a 1/8 scale model of the boattail device that would be used for performance testing in a wind tunnel,” said Patrick Ryan, President of ATS.
Generated by wind shaking off the main design is damper, and the jagged shape building through wind tunnel testing, to reduce 30-40% of the wind generated by shaking., Taipei 101, the foundation works to fight was 15 months in total, 150000 tons of soil excavated, piles of reinforced concrete form by the 382.
Siemens engineers spent about four months testing passenger coaches in a climate wind tunnel to validate the design of the heating, ventilation and cooling(HVAC) system. Now they use ANSYS Fluent computational fluid dynamics(CFD) software to validate the design before building the first coach to reduce the testing time and cost by up to 50 percent.

Everyone knows that the practice of hidden between mountains and rivers would be too romantic too unrealistic, but to find the same small town in Lijiang to leisure and some on the big difference- and there is no Jielu barren hills and trees and brought a single fishing series of daily inconvenience, mental cents but end up clear away wind tunnel itself.
But besides Pascal Wehrlein, they will also use one of our wind tunnels.".
