The Simulation of Virus-Laden Aerosol Particle Spread Inside a Passenger Ferry

This paper presents computational fluid dynamics (CFD) of Reynolds-Averaged Navier Stokes (RANS) simulations to analyse the flow movement of virus-laden particles inside an air-conditioned ferry cabin. Two major cases are investigated, the first cases is where one infected passenger sits on a passenger chair located closer to the edge of the cabin, and the second case is where the infected passenger is standing in the middle of the cabin. For each of these two positions, three air conditioner velocities were investigated. The results indicate that a low-velocity air conditioner inside a ferry cabin is more favourable than a high-velocity air conditioner because it tends to push the particles towards the floor and has less mixing effect. Such action would minimise the spread of the virus-laden particles, resulting in a more effective 1.5-meter social distancing rule.
