wind velocity

The setting up mode of wind force was advanced and let the wind velocity variable be introduced into the wind force model.

And it was seen from the wind tunnel tests that the wind pressure gradient had a nonlinear relationship with the wind velocity.

The wind-induced dynamic coefficients are little influenced by the wind velocity and tower elevation.

As the result, it is better to use the front of wind field and the wind velocity larger than 0. 7 times the maximum in the SMB method.

Presents a method to measure the wind velocity with the thermistor as the velocity sensor.

The momentum descending directly enhanced the surface wind velocity and sand dust.

The propeller can follow the wind velocity closely during high-speed gusts.

DFA - 2 speed wind table is a measure of average wind speed instrument, mainly used for coal mine average wind velocity measurement.

The higher and more dense vegetation grow, the effect stronger windbreaks show, and increases with the wind velocity.

The determination of the critical wind velocity is one of the main targets.

The buffeting displacement standard deviation might be higher than the mean value, even for higher wind velocity.

The response of porous fence to the near-surface airflow can be characterized quantitatively by sand particles threshold wind velocity.

In addition, the wind velocity computational formula of VAP method is improved.

Stubble strip of conservation tillage can lower wind velocity, conserve water and soil, resist wind erosion and protect strip ploughed land.

However, in the same wind direction, , the threshold wind velocity becomes smaller with the increment of the slope angle in leeward slope.

conductor's icing growth forms a parabolic relation with wind velocity and an exponential increasing relation with icing time.

A weather report provides examples of both types of field: temperature and pressure are scalars , whereas wind velocity is a vector.

Results indicate that the height of maximum horizontal wind velocity is correlative with the horizontal position.

The atmospheric boundary layer is simulated, and the corresponding logarithmic wind velocity profile and turbulence intensity are obtained.

Wind: velocity, direction, monsoon, atmospheric circulation.

The meteorological risk factors were: landing of typhoon, central pressure depression, wind velocity, and rainfalls .

The relation of the feature wind velocity between experimental and natural wind-wave is calculated and established.

The results showed that crop stubble could protect the adjacent bare field through decreasing wind velocity and erosion modulus.

The factor that influences rainfall mainly in Taiwan's winter and autumn is the elevation, and mainly in spring and summer is wind velocity.

The effects of flapping frequency, wind velocity, angle of attack, plane shape of wing and cambered aerofoil are investigated.

The wake galloping is a multiple-modes vibration and the mode participating levels vary regularly as wind velocity changes.

and the proved average wind velocity at the air outlets of the utility model is increased by 20 percent.

Through experimental test the safe wind velocity range of crosswind of roller coaster was obtained.

Simulation of stochastic wind velocity field is prerequisite to flutter or buffeting analysis of long-span bridges in time-domain.

(1) To criticise it for such failure is roughly comparable to criticising a thermometer for not measuring wind velocity.

moreover the deformation pattern of membrane changes when wind velocity increases.

The relocation of stations is the main cause of heterogeneity in wind velocity data.

Wind velocity and direction could hinder or enhance placement of cooling water streams.

It is certainly affected by changed wind velocity and relative humidity on compressive strength.

Wind direction, wind velocity, air temperature and air pressure have a very great effect on the propagation of pressure waves.

However, the increment of aperture or wind velocity can weaken thermal blooming oppositely.

According to the different wind direction, wind velocity and smoke vent area, five fire scenarios are built.

The mechanical ventilation psychrometer under the stable wind velocity can get the relative high accuracy standard.

Results showed, wind velocity factor is more related with rainfall.

The development of wind velocity and direction sensor at home and abroad is introduced.

Because there is no the actual measured time history of fluctuating wind velocity, the frequency-domain method can not be used.

It can generate maximum wind velocity of 15 to 20 metres per second, enough to simulate an F3-size storm.
