    • Analysis of parameters influencing pathogen concentration in a room with displacement ventilation using computational fluid dynamics and Taguchi methods 

      Yuce, Bahadir Erman; Aganovic, Amar; Nielsen, Peter Vilhelm; Wargocki, Pawel (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-30)
      Analyzing multiple physical factors simultaneously to determine optimal ventilation solutions can be challenging. Furthermore, this type of analysis needs a large case number to be investigated, making the problem’s solution unfeasible. This study tackled these challenges by integrating Computational Fluid Dynamics (CFD) with the Taguchi method to overcome these issues. Our previous research ...

    • Estimating the impact of indoor relative humidity on SARS-CoV-2 airborne transmission risk using a new modification of the Wells-Riley model 

      Aganovic, Amar; Bi, Yang; Cao, Guangyu; Drangsholt, Finn; Kurnitski, Jarek; Wargocki, Pawel (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-23)
      A novel modified version of the Wells-Riley model was used to estimate the impact of relative humidity (RH) on the removal of respiratory droplets containing the SARS-CoV-2 virus by deposition through gravitational settling and its inactivation by biological decay; the effect of RH on susceptibility to SARS-CoV-2 was not considered. These effects were compared with the removal achieved by increased ...

    • Modeling the impact of indoor relative humidity on the infection risk of five respiratory airborne viruses 

      Aganovic, Amar; Bi, Yang; Cao, Guangyu; Kurnitski, Jarek; Wargocki, Pawel (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-07)
      With a modified version of the Wells-Riley model, we simulated the size distribution and dynamics of five airborne viruses (measles, influenza, SARS-CoV-2, human rhinovirus, and adenovirus) emitted from a speaking person in a typical residential setting over a relative humidity (RH) range of 20–80% and air temperature of 20–25 °C. Besides the size transformation of virus-containing droplets due to ...

    • New dose-response model and SARS-CoV-2 quanta emission rates for calculating the long-range airborne infection risk 

      Aganovic, Amar; Cao, Guangyu; Wargocki, Pawel; Kurnitski, Jarek (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-14)
      Predictive models for airborne infection risk have been extensively used during the pandemic, but there is yet still no consensus on a common approach, which may create misinterpretation of results among public health experts and engineers designing building ventilation. In this study we applied the latest data on viral load, aerosol droplet sizes and removal mechanisms to improve the Wells Riley ...

    • Zonal modeling of air distribution impact on the long-range airborne transmission risk of SARS-CoV-2 

      Aganovic, Amar; Cao, Guangyu; Kurnitski, Jarek; Melikov, Arsen; Wargocki, Pawel (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-28)
      A widely used analytical model to quantitatively assess airborne infection risk is the Wells-Riley model which is limited to complete air mixing in a single zone. However, this assumption tends not to be feasible (or reality) for many situations. This study aimed to extend the Wells-Riley model so that the infection risk can be calculated in spaces where complete mixing is not present. Some more ...
