    • Validation of air ventilation in tunnels, using experiments and computational fluid dynamics 

      Myrvang, Torgeir; Khawaja, Hassan (Journal article; Tidsskriftartikkel; Peer reviewed, 2018)
      The study presented in this paper concerns the ventilation system inside tunnels. The ventilation system is responsible for the removal of exhaust gases produced by vehicles and for providing a clear view throughout the tunnels in routine operations and in the event of fire. The ventilation system has several stages, which are equipped with one or more fans and can be activated together or separately. ...

    • Ventilation design conditions associated with airborne bacteria levels within the wound area during surgical procedures: a systematic review 

      Aganovic, Amar; Cao, Guangyu; Fečer, Tomáš; Ljungqvist, Bengt L.; Lytsy, Birgitta; Radtke, Andreas; Reinmüller, Berit; Traversari, Roberto A.A.L. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-26)
      Without confirmation of the ventilation design conditions (typology and airflow rate), the common practice of identifying unidirectional airflow (UDAF) systems as equivalent to ultra-clean air ventilation systems may be misleading, but also any claims about the ineffectiveness of UDAF systems should be doubted. The aim of this review was to assess and compare ventilation system design conditions for ...

    • Windtech Technology - Measuring Cold Exposure via Conjugate Heat Transfer 

      Khawaja, Hassan (Conference object; Konferansebidrag, 2020)
      Windtech technology is based on a novel patented technique of measuring cold exposure (UK Patent Office Application Number: 1914757.8, titled: Measuring cold exposure, dated: 11th October 2019). In this technology, the cold is measured via the response of an electrical heater exposed to environmental elements such as ambient temperature, wind, humidity, and irradiance. In this technology, the heater ...

    • Windtech – A Sensory Device for ‘Cold’ Sensation Measurements 

      Leyli, Amir Nadem; Khawaja, Hassan; Antonsen, Ståle; Swart, Daniel Kristoffer (Journal article; Tidsskriftartikkel, 2021-12-21)
      Windtech device is a novel tool for measuring the sensation of the ‘cold’. Cold poses numerous challenges for industrial operations, human survival, and living convenience. The impact of the cold is not possible to be quantified just based on temperatures; however other factors such as wind speed, humidity, irradiance have to be taken into consideration. Efforts have been made to develop combined ...

    • 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 ...
