Why you should open your windows while eating Christmas dinner


Open your windows while having Christmas dinner: The simulation shows how fresh air throws away coronavirus particles in the dining room.

  • This simulation was created by experts from Hexagon Manufacturing Intelligence in Japan.
  • Seeing what happens to the particles that come out of the mouths of infected people
  • Opening windows and doors shows improved ventilation that has a significant effect on the number of infectious particles in the room

The shocking new video reveals the dangers people take by having a Christmas dinner with people from another household.

It shows how in a British dining room coronavirus particles are carved out of one’s mouth and infect others.

Experts from Hexag Man Manufacturing Intelligence in Japan created a model to show the level of risk that an asymptomatic person poses at the table for others.

Engineers hope their simulation can help individuals and families assess the risk involved during the festive period.

Researchers worked on the dimensions of the room 4 .. 4. MX 7. 3. M (116 ft x 16 ft) and ran two versions of their simulation, in which the room was closed without any ventilation (left) and the other two windows and door were open. , Everyone for ten minutes (right)

The researchers worked on the dimensions of the room at 4.9 mx 3.7 m (16 ft x 12 ft) and ran two versions of their simulation, in which the room was closed without any ventilation and the other two windows and door were open, each for ten minutes.

In the videos, researchers routinely map the particles emitted from a person’s mouth while breathing and talking.

This causes pedestrians to disperse in proportion to the particles rather than coughing or sneezing.

“Hexagon engineers in Japan created the simulation as part of a public education effort to help authorities and the general public better understand how to best protect themselves and each other from COVID-19 transmissions,” Hexagon’s industry director Keith Perry told MaxNline.

‘Being Japanese, they have social distance and PPE during illness. Wearing, so interested in other trends. ‘

Heat from radiators, food and people, pushes particles towards the umbrella, but if there is insufficient ventilation they have nowhere to escape and are forced to move down and move around the room.

However, if there is adequate ventilation from open windows, the particles are sucked almost immediately and away from others.

Mr Perrin said, ‘Good ventilation is key – make sure there are as many windows and doors open as possible to help spread air and increase particles.’

Heat from radiators, food and people, pushes particles towards the canopy, but if there is insufficient ventilation they have nowhere to escape and are forced to move down and wander around the room.

If there is adequate ventilation from open windows, contagious

If there is adequate ventilation through open windows, infectious particles are drawn almost immediately and away from others.

‘Social distance is important regardless of ventilation in the room, but it does not fail – uncontrolled simulation shows that the number of infected particles increases and travels more than the minimum of 2m of the recommended distance, so getting airflow into the room is very difficult. Important to maximize the effectiveness of social distance.

‘However, at the end of the segment, there are some elements compared to the effect of an open window.’

He said that based on his calculations, an infected person in an uninfected room infects six more people.

However, in a ventilated average dining room, statistically no one else will be infected.

‘These simple efforts lead to significant statistical changes.

‘Assuming similar situations, to give you a little idea during three transmission iterations, those 215 less people in math have been infected!’ He says.

‘Our study shows that it is not a question of’ if ‘transmission, it is a question of’ when ‘. “

The team at Hexagon used their majesty during the epidemic and to show people how invisible droplets and aerosols spread without people knowing.

One of his videos shows how sneezing with the elbow is better than not stopping at all, but can still endanger those close by.

Another visualization showed what happens if a person does not wear a mask in a tube or train.

How to walk on a narrow corridor behind an infected person increases the risk of catching Covid-19

Coronavirus particles that come out of a person’s open mouth in a tight space like a corridor linger for many seconds behind them, a study warns.

The discovery comes from computer simulations that show how particles behave after being gnawed by someone moving forward.

Floating air and vortices keep the particles floating in the air at waist height behind the infected person, which poses significant problems for social distance and increases the risk of infection for children.

Researchers at the Chinese Academy of Sciences in Beijing, for example, used a 1.8m (5ft 11in) man running at 1.5m / s (3.5mph).

They modeled what would happen if he calmed down without a tight mask, both on the wide open spaces and on a narrow corridor.

Previous studies have focused almost exclusively on the spread of infectious particles in places where there are no limits. This new study examined how particle behavior differs if they are physically written.

They found that when walking in confined spaces, airborne droplets carrying a deadly virus followed a special pattern, called a ‘detected mode’.

The computer visualization shows that particles flow behind a person through the air currents that follow them and the cloud of drops separates from the body and forms an extinct ring of infectious aerosols behind some of the person’s feet.
