摘　　要：This study investigates the airborne transmission of virus-laden droplets generated by a cough of patients in an aircraft cabin to reveal the infection risk of taking an airplane.The influence of the ventilation system on the flow feld of the cabin was analysed to reveal its effects on the airbore transmission ofvirus-laden droplets.Meanwhile.human body heat was also considered in the simulations.The results show that hot plume due to human body hent has a significant impact on the upward movement of virus-laden droplets.The virus-laden droplets expelled by a cough can be transmitted to the region two to three rows away from the generator.Particularly,the transverse motion present in the early stage of the droplet transmission results in a high infection risk to the passengers in the same row as the patient.This work gives insight into the understanding of the airborne transmission of virus-laden droplets in the entire passenger cabin.
