direction and wind velocity measuring instrument to accurately measure the direction and velocity of an air current generated in a closed space even when the air current is very weak and, at the same time, to make the handling and operation of the instrument easier at the time of measurement....
EXAMPLE OF ENERGY LOSS IN A 24 MW WIND FARM Studies show even small wind direction measurement errors have a dramatic negative impact on total wind farm power output. *Resource assesment carried out in windPRO to study how incorrect wind direction measurements can dampen the power output in a ...

A which possesses Out the entrance of the wind or B can be provided and is provided in ventilation trunk, A or B when the wind flowed, ventilation trunk in the particular ventilation trunk A or B and, the wind direction measurement equipment 1 which it possesses.< Choice figure >Drawing ...
The exposure of the building can be classified into two categories (open country and suburban) depending on the wind direction. A roof corner panel with 12 tappings has been constructed as a separate unit and has been attached to the roof. Instrumentation for the measurement of mean pressures ...
of space and time scales. More sophisticated measurement and visualization techniques applied from the mid 1960s onward, however, began to reveal that different turbulent flows were dominated by eddies of quite different character and that the average properties of the different flows, such as their...
We compiled a very extensive dataset utilizing nine portable sensor array modules – each endowed with eight metal oxide gas sensors – positioned at six different line locations normal to the wind direction, creating thereby a total number of 54 measurement locations. In particular, our dataset con...
