Mitigation Of Traffic Pollution Through Application Of Venturi Effect

The principle problem addressed in the conducted research was the issue of excessive pollution being emitted from Beijing’s most congested interchanges which contributes to the overall poor air quality.The main aim was to examine which principles could be applied through architecture for assisting in the process of pollution mitigation.The first objective of this research included detecting and precisely mapping the biggest pollution contributors among Beijing’s interchanges,and thus defining spots in the city that are in need of urgent air remediation.Secondly,the research dealt with introducing Venturi scrubber as the possible pollution mitigator.As it already proved highly effective and successful in the process of treating pollution for the purposes of industry,this research aimed to prove that the same method could be applied for the abatement of traffic induced pollution.Other than this,since Venturi scrubbers usually operate on a much smaller scale that does not conform with architectural one,it was necessary to examine whether this principle could be used on a large scale with the same efficiency.For this reason,series of simulations have been conducted to see how the airflow performs in large structures atria observing criteria such as velocity and pressure loss.Based on the simulations,an optimal model was adopted for the proposal of Venturi towers.The final objective of the research included the proposal for towers,which introduced how a megascaled Venturi scrubber can be implemented in the context of the city.The previously marked interchanges were used as a platform where these towers could be installed,reestablishing concepts such as role of infrastructural buildings in the city context,providing land from traffic infrastructure,but most importantly,concept of integrating mechanical and architectural features of the building in one hybrid entity.The project for Venturi towers provides a proposal how a problem of traffic induced pollution can be treated from an architectural point of view.In the project this was achieved through employing atrium of a high-rise building,which centrally serves for air treatment,and peripherally for inhabiting.So,on a much broader level,it illustrates the beneficial possibilities of merging mechanical and architectural features into one autonomous building that would be both serviced and serviceable for itself and the city.
