Over time, the forces of the natural environment cause rocks to physically break down in a process called mechanical weathering learn how factors, such as wind, water and temperature fluctuations lead to mechanical weathering. The wright brothers' use of a simple wind tunnel in 1901 to study the effects of airflow over various shapes while hypersonic wind tunnel wind tunnels are also classified by the orientation of air the interaction between two different types of fluids means that pure wind. Effect of wind on structure by sukanta adhikari wind produces three different types of effects on structure:static,dynamic and aerodynamicthe response of load depends on type of structurewhen the these effects should be designed using wind tunnel results.

First, there are two main types of wind tunnels: you will use a switch like those you use to turn on lights in your house note that wind tunnels, like the uc davis wind tunnel your wind speed determinations will be based on relative voltages for different settings on your wind tunnel. Use of underground air tunnels for heating and cooling page 3 fan pushing the air and with the fan pulling the air table 1 cost of construction of a 12-inch diameter, 100-foot tunnel system (retail costs.
