Airflow distribution for minimizing human exposure to airborne contaminants in healthcare facilities
Aganovic, Amar (Doctoral theses at NTNU;2019:41, Doctoral thesis, 2019)Hospital-acquired infections (HAIs) have been a persistent problem in hospitals for over a century and are associated with significant mortality, morbidities and increasing healthcare cost. There is strong evidence that ... -
Analysis of dynamical behaviour of the boiler room at Mechanical Engineering Faculty in Sarajevo in standard exploitation conditions.
Aganovic, Amar (Master thesis, 2013)ynamical analysis of the boiler room behaviour will be conducted by using state of the art software packages and available libraries for modelling and simulation of the HVAC systems. Mathematical model for transient analysis ... -
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 (Peer reviewed; Journal article, 2021)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 ... -
Experimental and simulated evaluations of airborne contaminant exposure in a room with a modified localized laminar airflow system
Cheng, Zhu; Aganovic, Amar; Cao, Guangyu; Bu, Zhongming (Peer reviewed; Journal article, 2021)The traditional mixing ventilation is not an energy effective approach to remove indoor air pollutants, maintain breath zone air quality, and control the airborne transmission. This study investigated the potential of a ... -
Experimental study of the interaction between thermal plumes and human breathing in an undisturbed indoor environment
Cheng, Zhu; Cao, Guangyu; Aganovic, Amar; Li, Baizhan (Peer reviewed; Journal article, 2020)This study characterized the interaction between human thermal plume and breathing air flow while people are sitting in a quiescent indoor environment. A sitting breathing thermal manikin was developed to mimic a real ... -
Experimental study on the effect of ventilation airflow rate and separation distance on the risk of airborne COVID-19 infection
Ruud, Mathilde (Master thesis, 2022)Koronapandemien har vart i nærmere tre år og påvirket menneskers liv med inngripende tiltak for å redusere smitte. Viruset har fortsatt å utvikle seg, selv med forholdsregler og distribusjon av vaksiner. Eksperter fra hele ... -
Experimental study on the exposure level of surgical staff to SARS-CoV-2 in operating rooms with mixing ventilation under negative pressure
Bi, Yang; Aganovic, Amar; Mathisen, Hans Martin; Cao, Guangyu (Peer reviewed; Journal article, 2022)The purpose of this study was to reveal the exposure level of surgical staff to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from the patient's nose and wound during operations on COVID-19 patients. The ... -
Experimental Study on the Surgical Microenvironment in an Operating Room with Mixing Ventilation under Positive and Negative Pressure
Bi, Yang; Heggebø, Frida Josefine; Harsem, Trond Thorgeir; Mathisen, Hans Martin; Aganovic, Amar; Cao, Guangyu (Chapter, 2021)Due to the outbreak of Covid-19, negative pressure operating room (NPOR) are strongly recommended to be applied to prevent spreading virus from infected patients to adjacent rooms during surgery procedures. However, there ... -
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; Peer reviewed, 2022) -
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 (Peer reviewed; Journal article, 2022)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 ... -
A systematic review of operating room ventilation
Sadrizadeh, Sasan; Aganovic, Amar; Bogdan, Anna; Wang, Cong; Afshari, Alireza; Hartmann, Anne; Croitoru, Cristiana; Khan, Amirul; Kriegel, Martin; Lind, Merethe; Liu, Zhijian; Melikov, Arsen; Mo, Jinhan; Rotheudt, Hansjörg; Yao, Runming; Zhang, Yixian; Abouali, Omid; Langvatn, Håkon; Sköldenberg, Olof; Cao, Guangyu (Peer reviewed; Journal article, 2021)Ventilation systems are the primary way of eliminating airborne pathogenic particles in an operating room (OR). However, such systems can be complex due to factors such as different surgical instruments, diverse room sizes, ... -
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. (Peer reviewed; Journal article, 2021)Background 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 ... -
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 (Peer reviewed; Journal article, 2022)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 ...
