ABSTRACT

Through the application of computational fluid dynamics theory and simulation technology to the simulation of the spread of the new crown pneumonia epidemic on cruise ships, two representative and typical simulation models of cruise ship narrow passages and land hotel passages were constructed, and the total release rate was established. The main technical parameters, such as flow interruption intensity, inlet speed, etc., are used as boundary conditions such as flow inlets and outlets, wall boundaries and other factors. Discrete format three-dimensional simulation calculations using adult sneezing droplets spreading in the local space as the scene are studied and calculated. The droplet diffusion distance in the narrow channel can reach up to 6m, which is three times the result of the hotel channel on the shore. The analysis puts forward the conclusion that the risk of droplet diffusion in the narrow channel space of cruise ships is higher than that in the open space.
