Distribution of droplet aerosols generated by mouth coughing and nosebreathing in an air-conditioned room
Zhang, Yixian; Feng, Guohui; Bi, Yang; Cai, Yilin; Zhang, Zheng; Cao, Guangyu (Peer reviewed; Journal article, 2019)The objective of this study is to understand the distribution of droplet aerosols in an air-conditioned room, which is very important to comprehend how infectious bacteria and viruses transmit from person to person through ... -
Energy efficient airflow distribution methods for surgical microenvironment control in operating rooms
Bi, Yang (Doctoral theses at NTNU;2024:13, Doctoral thesis, 2024)With approximately 300 million surgeries performed worldwide each year, the operating room (OR) environment plays an important role in creating a satisfactory setting for all occupancies. However, there are currently several ... -
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 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 ... -
Experimental study on the thermal plume from a surgeon in an operating room with mixing ventilation during COVID-19 pandemic
Heggebø, Frida Josefine; Bi, Yang; Harsem, Trond Thorgeir; Mathisen, Hans Martin; Cao, Guangyu (Chapter, 2021)Following the outbreak of COVID-19 (SARS-CoV-2) in 2019, studies show positive results in protecting the surgical staff from patients infected by COVID-19 in operating rooms (ORs) with negative pressure. A negative pressure ... -
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) -
Numerical simulation of the airborne transmission of COVID-19 due to respiratory activities under different ventilation conditions.
Quesnel, Allan (Master thesis, 2022)Covid-19 pandemic have recently raised lots of issues about the way we lived socially and have led to various studies for our social behaviour to be adapted to struggle the crisis. This report presents the work done during ... -
Numerical simulation of thermal environment at different relative humidity levels in one operating room of St. Olav’s hospital
Fečer, Tomáš; Solberg Hatten, Thea; Bi, Yang; Cao, Guangyu (Journal article, 2021)This study investigated the influence of three different levels of relative humidity, 20%, 40%, and 60% on the thermal comfort of surgical patient and staff in one operating room of St. Olav’s hospital with mixing ventilation. ... -
Reducing the risk of viral contamination during the coronavirus pandemic by using a protective curtain in the operating room
Sadeghian, Parastoo; Bi, Yang; Cao, Guangyu; Sadrizadeh, Sasan (Peer reviewed; Journal article, 2022)Background Airborne transmission diseases can transfer long and short distances via sneezing, coughing, and breathing. These airborne repertory particles can convert to aerosol particles and travel with airflow. During ...
