Annotation: The work is devoted to determining the influence of the geometric shape and design parameters of frameless arched coverings on air mobility in a ventilated layer by experimental static modeling of air mobility in a ventilated air layer. Numerical simulation is performed using the SolidWorks software package for modeling the flow of liquids and gases based on the solution of the Navier-Stokes equation. The trajectories of wind flows, patterns of changes in speed and wind pressure when flowing around frameless arched coverings of different geometric shapes are shown, and the values of external air flow parameters at control points are determined. It is established that the geometric shape affects not only the air velocity in the ventilated layer, but also its direction. It was found that an increase in the height of the arch for semicircular coverings and coverings with two curves leads to an increase in the air velocity at the entrance to the vent, and for gable arches – on the contrary, to a decrease.
Keywords: insulated frameless arched coating, geometric shape of the coating, structural parameters of the coating, ventilated layer, air mobility, air flow direction.
