The simulation provided by SIMULIA looks into the potential spread of COVID-19 in an air-conditioned vehicle; also usable for office space design and PPE production

The COVID-19 pandemic has caused the entire world to re-approach every single form of living essentially, with major concern around health and safety of each and every individual. The need for social distancing to contain the transmission of the corona virus has become an important aspect of everyday existence. The use of Personal Protection Equipment (PPE) has also become very appropriate to help cut the transmission of the disease further.

Now, with lockdowns being relaxed around the globe, more people come into contact with each other. Even when following social distancing measures, the possibility of transmitting the virus while sneezing is very high. This has led simulation software provider Dassault Systemes to develop simulation scenarios of a human sneeze and the possible trajection of pathogens. It has produced this simulation in its SIMULIA product, which is powered by the 3DEXPERIENCE Platform and delivers realistic simulation applications.

The simulation shows how a human sneeze carries various particles in a closed car cabin with airflow from a typical air-conditioning system. It clearly demonstrates that sneeze particles are easily transmitted to nearby occupants very quickly. Depending on the airflow direction and speed, particles will travel and hover inside the cabin before eventually falling to the vehicle floor, noted Dassault Systemes. The company explained that while obviously not all the particles ejected from a sneeze are contagious, it is likely that some carrying a virus or bacteria could reach a neighbouring occupant. This simulation can be used to create similar simulations for use in airplane cabins, offices, or even outside.

Airflow and direction play a big role in particle distribution and therefore state-of-the-art turbulent models and particle tracking capabilities are required for accurate simulation. The results gathered from these simulations have the ability to help vehicle engineers develop and design vehicle cabins and air-conditioning vents according to required safety measures. It can be mentioned that simulation-driven design minimises costs and risks during product development.
