Annotation: Otvory (podjazdy, podchody, pasáže) v budove výrazne modifikujú vzduchový prúd sprevádzaný redistribúciou tlakov. Spôsobujú spojenie oblasti vysokého kladného tlaku na náveternej strane budovy a záporného tlaku (sania) na záveternej strane budovy indikovaním rýchleho prúdu podmieňujúceho vysoké sania v analyzovanej pasáži (podchode, podjazde) - výrazný aerodynamický diskomfort a redukujúceho sanie na záveternej strane budovy. Kvantifikácia efektu penetrácie prúdu bude realizovaná experimentmi v aerodynamickom tuneli na tuhom modeli, matematickými modelovými simuláciami za využitia nástrojov CFD a ich vzájomnými konfrontáciami. Kvantifikované budú vplyvy smeru vetra, rozmerov podjazdu (podchodu, pasáže), rozmerov budovy na rýchlosť prúdu v priebežnom prúdení a možnosti eliminácie efektu penetrácie prúdu.
Annotation in English: Holes (underpasses, subways, passages) in the building significantly modify the air flow associated with redistribution of pressures. It cause the connection of the session of the higher positive pressure on the windward side of the building and the negative pressure (suction) on the leeward side of the building, indicated by the rapid flow geared to the high intake of the analyzed passage (subway, underpass) - significant aerodynamic discomfort and reducing the suction on the leeward side of the building. Quantification of the effect of flow penetration will be carried by experiments in a wind tunnel on a solid model, by the mathematical model simulations using CFD tools and their mutual confrontation. It will be quantified impacts of wind direction, the dimensions of underpass (subway, passages), the dimensions of the building on the speed of the flow in the interim, and the elimination of the effect of flow penetration.
