Title: Comparative analyses of air flow characteristics, through two variants of prototyped device for fine dust particles concentration measurement
Keywords: CFD, Flow modelling, Fine dust particles
Abstract: This paper presents an innovative measuring device, designed to raise the awareness of the population about ambient air quality in the urban environment. The main aim of the study was better understanding of the air flow through a prototyped device, for fine dust particles measurement, in order to improve its performance with means of numerical simulations. To achieve the goal, two design versions of the protective box were assessed with CFD modelling. In the first one, there is a so-called “protective cavity” – a free volume of air prior to the main sensor position. In the second design, this cavity does not exist and the sensor contacts through extruded circular opening with the environment. A comparative analysis of the two variants is represented by velocity and relative pressure fields’ visualizations.
