This article describes the formula determining the temperature, velocity and force of wind flow around the buildings. The dependence of wind speed and temperature difference, showing the distribution of aerodynamic coefficients on the facade of the building in different directions of wind flow. The basic building envelope and the effect of surface roughness on the flow around buildings.

At work investigates the incoming flow and its alignment to the ventilation system elements, located directly outside a radial fan. The efficiency of the ventilation system depends on the improvement of its aerodynamic components. Of great importance are placed the elements directly outside a radial fan. The attention paid to the improvement in work mode energy efficiency of ventilation systems alignment the incoming flow of radial fan the variable modes of its work.
