We have to concern reduce the risk of COVID-19 in the classroom through simulation. With the outbreak of the new crown epidemic in 2020, people around the world are staying as normal as possible while waiting for vaccination while avoiding infection. Unfortunately, it is not normal to work as usual to maintain health. But there are ways to reduce the risk of disease. Through the simulation, we have to safety precautions in the classroom.
Our biggest concern is our educational facilities and the safety of our youth. Some schools have adopted all online learning. But many schools are still open to ease the pressure on working parents and at the same time allow children to learn in as normal an environment as possible. It makes sense, but parents are worried. That they want to know. What the school is doing to ensure the safety of its children.
Using high-precision computational fluid dynamics (CFD) simulation software, was instrumental in improving the safety of students during an influenza pandemic. Researchers used simulations to analyze three factors that can inhibit transmission and make students especially safe wearing masks, ventilation, and seating. we have to safety precautions in the classroom through simulation.
Classroom precautions during COVID-19 show through simulation: COVID-19 has been shown to spread through the mouth and nasal secretions. Which extends into the air through droplets of various sizes (including terrifying aerosols) such as sneezing, coughing, and even talking. By this time, most people know that masks are a very effective way to prevent the spread of water droplets from person to person. Mask is the best choice in universal precautions in the classroom.
Simulation experiments have proved this. However, some schools do not require students to wear masks. Even schools with masks require students to take off masks for lunch. As children, they cannot apply masks immediately after eating, and sometimes they may remove the mask. Or may wear it incorrectly. Therefore they require the next line of defense.
Ventilation is good for COVID-19 in the Classroom
Ventilation is the key. A good ventilation system can bring air droplets out of orbit, and then they can land. Or can be breathed by students and teachers. It also helps reduce areas of high droplet concentration, which may be associated with a higher risk of infection. Simulation results show. That is a normally ventilated classroom, that is when the windows are opened and the wind is blowing.
So only 14% of water drops leave the orbit within a minute. When the spare side exhaust fan is on. So the percentage increases to 20%, and when the central exhaust fan is turned on. So the percentage increases to 22%. Therefore, forced ventilation, particularly effective central heating, ventilation, and air conditioning systems, is the main factor in removing water droplets from the room before infecting anyone. There are universal precautions ideas in the classroom.
Seat arrangement: Covid-19 classroom rules
- Also important is the interpersonal position distance between students. A recent study put forth the following hypotheses:
- The room temperature is 26 ° C
- Each student is equally likely to be the source of the pathogen
- Viral load is 900 grains per hour
- The average diameter of the particles is 1 μm
- The single pollution path is through aerosols (small droplets in the air).
Count the three classes separately: one class has 40 students, and the other two have 20 students. Using the most advanced engineering methods and lots of operations, the research unexpectedly found the optimal layout from 20 students, the configuration is shown below. Compared to the traditional maximization of the distance between students, the distribution of air in the room leads to the expected layout. This is due to the specificity of ventilation. Therefore each room has its own independence. Good seat arrangement is essential & this is the first choice for safety precautions in the classroom
According to the simulation results, this is the best in covid classroom ideas, a room with 20 students with a central exhaust fan is the safest environment for children in the epidemic. It is safe if these students wear masks. Mask has the first choice in universal precautions in the classroom.
Although there is no foolproof way to ensure this. That someone is 100% free of COVID-19 (leaving absolutely no contact with others), the simulation can correctly assess an environment and allow engineers to safely configure an environment until the vaccine arrives Can give – not only in the classroom but also in the hospital, in the workplace.
