The COVID-19 is a severe respiratory disease caused by a devastating coronavirus family (2019-nCoV) has become a pandemic across the globe. It is an infectious virus and transmits by inhalation or contact with droplet nuclei produced during sneezing, coughing, and speaking by infected people. Airborne transmission of COVID-19 is also possible in a confined place in the immediate environment of the infected person. Present study investigates the effectiveness of conditioned air released from air-conditioning machines to mix with aerosol sanitizer to reach every point of the space of the isolation room so as to kill the COVID-19 virus which will help to protect the lives of doctors, nurses and health care workers. In order to numerically model the laminar-transitional flows, transition SST k-ε model, which involves four transport equations are employed in the current study. It is found from the analysis that high turbulent fields generated inside the isolation room may be an effective way of distributing sanitizer in entire volume of isolation room to kill the COVID-19 virus.

COVID-19 是一种由毁灭性的冠状病毒家族 (2019-nCoV) 引起的严重呼吸道疾病，已成为全球流行病。它是一种传染性病毒，通过吸入或接触感染者打喷嚏、咳嗽和说话时产生的飞沫核进行传播。 COVID-19 也可能在感染者周围环境的密闭场所内通过空气传播。目前的研究调查了从空调机释放的空调空气与气溶胶消毒剂混合以到达隔离室空间的每个点以杀死COVID-19病毒的有效性，这将有助于保护医生、护士的生命和医护人员。为了对层流过渡流进行数值模拟，本研究采用了涉及四个输运方程的过渡 SST k - ε模型。分析发现，隔离室内产生的高湍流场可能是在隔离室的整个体积内分配消毒剂以杀死COVID-19病毒的有效方式。
