CFD Simulation on the Role of Mask for Protection Against COVID19

COVID19 Pandemic has been a serious and worrisome pandemic that seems to create medical as well as economical problems for the world. Unfortunately, neither vaccine nor 100% reliable treatment exists for the new Coronavirus Pandemic across the world.

Computational Fluid Dynamics may be the key in understanding the fluid dynamics of the coronavirus transmission and coronavirus exposure. Many medical experts agree that the best way to help protect yourself is to use a facemask as per WHO guidelines and US CDC recommendations.

You can see the effect with and without mask using the Computational Fluid Dynamics simulation below:

 

Evidence of Airborne Transmission of the Severe Acute Respiratory Syndrome Virus

Here is a very good scientific article about Evidence of Airborne Transmission of the Severe Acute Respiratory Syndrome Virus. It may be relevant to coronavirus research and use of computational fluid dynamics CFD.

Computational Fluid Dynamics and Fight Against COVID19

Computational Fluid Dynamics or CFD is more important then ever in a fight against the COVID 19 Pandemic. Its possible to simulate various means of the transmission of the disease through air using CFD simulations. For example, CIMNE researchers are applying computational fluid dynamics models coupled with particle-based models to the simulation of the flow of virus in the air produced by a sneeze. This research is carried out in close cooperation with the group of Professor Rainald Lohner at George Mason University in the USA. Prof Lohner, who is also the PI in this research activity, is an affiliated scientist to CIMNE where he spends 2-3 months research periods every year since 1995.

These virus flow simulations will be useful for predicting the distribution of virus in the air in closed and open environments, such as hospitals and supermarkets, among others. These predictions will be more relevant in highly populated spaces, such as airports or crowded hospitals.

The problem is particularly important to face the challenges that the Covid-19 crisis is posing to society. Many doctors, nurses, TSA personnel etc. can be infected needlessly because airflow is poorly understood or neglected. In order for the virus not to spread through medical facilities infecting people, the airflow needs to be managed so that no particles from rooms with Codiv-19 patients leave those rooms.

Furthermore, by being able to predicting how the airflow inside high-risk rooms is, the medical staff could position themselves so that the chances of infection are minimized. By using simulation technology these flows can be computed and the airflow can be optimized so that further infections are minimized.

Importance of CFD in Engineering

One of the biggest problems that Engineers face today is that they dont have an ability to test their systems and their designs effectively due to high cost of experimental setups. Luckily with the usage of CFD or Computational Fluid Dynamics, it has become easy to be able to simulate the behavior of your design as far as fluid flow and fluid interactions are concerned. Especially in today’s world, almost everything interacts with some sort of a fluid such as water, air, oil, chemical substances etc.

In CFD, you will need to first create a simulation of your design using various mathematical techniques and software available to you. It is a time consuming process, but you can be sure that it will be a very useful process for you as an engineer.

There is great demand all over the world for engineers who know CFD and you should also make an effort to learn CFD today.
