where ρ is the air density, U is the mean air flow velocity, r is the local blade radius, ω is the blade angular rotational speed, a and a′ are the axial and the tangential induction factors, respectively.
The results show that, in the horizontal direction, the simulated distribution of wind speed and mean air temperature at 1.5 m height were closely related to the spatial distribution of the underlying surface types.
Based on the comparison of the overall performances, it was found that the SVM6 and ANFIS6 models which require mean air temperature, relative humidity, wind speed and solar radiation input variables had the best accuracy.
Such criteria should include space temperature and humidity, air speed surrounding occupants, mean radiant temperature, indoor air quality requirements, and sound and vibration levels.
The mean wind speed was 1.4 m/sec and mean air temperature was 21 degreesC.
Changes in the down-force, drag, downstream mean exhaust plume concentration and the mean air quality concentration for nearby pedestrians/cyclists are estimated for differing vehicle speeds.
This data includes daily mean air temperature, dew point (minimum, mean and max), relative humidity (minimum and maximum), maximum wind speed, air pressure (minimum and maximum) as well as maximum solar radiation.
The impact of street orientation relative to prevailing winds and the resulting effects of ventilation (air speed and spatial distribution) on the dispersion of traffic-generated air pollutants were additionally analyzed by means of computer simulations.
The air speed measurement is also valuable during this phase.
The relative air speed is about 0.1 m/s.
