Indoor environment simulation of polluted area in hall A of Dahuashan cabin hospital

Carries out a numerical simulation on the indoor environment of the polluted area in hall A of Wuhan Dahuashan cabin hospital. Analyses the temperature field and flow field of the polluted area. The results show that the environment of the polluted area basically meets the thermal comfort needs of patients, but the thermal stratification is still exist with the vertical temperature difference up to 6.5 ℃. The wind speed in the living area of patients conforms to the requirements of the standards, but the overall ventilation effect is poor, with high wind speed near the door, and a blind area at the height of the breathing area in the central region. Due to thermal stratification and poor ventilation, pollutants and viral droplets exhaled by patients are easy to accumulate, which increases the probability of cross-infection among patients and the work risk of medical staff.
