Abstract


Coronavirus Disease (Covid-19) becomes a serious attention because the virus can spread from human-to-human rapidly. By the first case at December 2019, Covid-19 was making the outbreak all over the world just in few months, especially since February 2020 until now. As a result, the pandemic makes hospital occupancy really high. Hospital must make strategy to make sure the isolation rooms are sterile. By knowing the best configuration for the isolation room and sanitizing machine for spreading disinfectant aerosol, modelling can be used to minimize the high risk from the virus inside the room, as the virus can be transmitted in the airborne. In this study, CFD modelling is used to answer this problem by modelling 3 rooms with different amount of beds. Room 1 contains of 2 beds, room 2 contains of 3 beds and room 3 contains of 6 beds. SST k-ε equation is used to model the flows. It is observed that the room with 6 beds has the biggest turbulence kinetic energy and high turbulence will be the best effective way to distribute aerosol from sanitizer to entire room.
