Simulation of a human sneeze will help in the design of protection products against the corona virus

The COVID 19 community established within Dassault Systèmes' Acceleration Program provides scientific simulation of human sneezes to support the design of PPE (Personal Protective Equipment) products

Dassault Systèmes uses a scientific simulation of human sneezing to support the development of personal protective equipment (PPE) projects, within the framework of the open online community of COVID 19 belonging to the Dassault Systèmes acceleration program DEXPERIENCE LAB3. This initiative is being carried out as part of the company's effort to provide optimal medical solutions and meet the urgent needs arising following the global corona crisis. During sneezing, various pathogens spread into the air, including the COVID-19. These simulations demonstrate what actually happens when a person sneezes and thus help with the need for the appropriate development of various personal protective products.

Dassault Systèmes used the simulation applications of the SIMULIA PowerFLOW software to develop a computational simulation of a human sneeze, with the aim of providing insights into the flow physics of the human sneeze. Dassault Systèmes' SIMULIA software is already widely used in the aerospace industries to produce dynamic simulation of fluid and air flow.
The scientific simulation of the human sneeze with the help of SIMULIA is based on data such as the speed of the exit of the various particles from the mouth during the sneeze, as well as the size of the particles and the spread of the various liquids. The end result is a realistic model of sneezing that is demonstrated in the video and shows the paths of the various mucus particles emitted into the air during sneezing, and where they settle when the person is equipped with personal protective equipment. These are efficient and computational simulations that enable rapid research for the purpose of customizing the design of personal protective equipment, whether it is the length of the product, its width or determining the distance between the various parts of the product.

Dassault Systèmes' acceleration program, the 3DEXPERIENCE LAB, has launched many initiatives for the purpose of leveraging collective collaborative intelligence and developing customized solutions that will assist hospitals in the fight against the corona virus. As part of this program, a fruitful collaboration was created between designers, engineers, scientists and various manufacturers who joined together in order to plan, engineer and produce quick solutions that meet the various needs that arise as part of the global fight against the spread of the virus.
