Abstract
To stop the spread of COVID-19 during the current pandemic, several measures such as the social distance restriction have been implemented. However, the magnitude of the restriction differs per country. In this study, the social restriction measure is being investigated from a mathematical perspective. A 2-phase simulation is set up in ComFLOW to investigate the horizontal displacement of a water droplet from a person’s mouth or nose to the ground. To verify the results from ComFLOW, first an ODE model is derived. The results of this model are generated with the use of MATLAB. When the maximum velocity was considered, this resulted in a required social distance of 1.32 meter. To achieve a credible model, several attempts have been made in ComFLOW. In the final attempt, the droplet starts in a tube, which is made of ellipses and rectangles to create a positive horizontal velocity with the use of gravity. The simulations in ComFLOW show that the simulation of a small droplet is not computationally efficient and causes the droplet to spray out. Increasing the viscosity of the water is beneficial for the simulation, yet it causes a longer computational time. In conclusion, comFLOW is a not an ideal program for simulating a flying water droplet.
