For decades, Computational Fluid Dynamics (CFD) has been a versatile tool for the industry. It answers research problems that focus on the flow of gases or fluids in a three-dimensional environment.
For example: What is the optimal structure of a boiler or an air conditioning system? Or: How can you execute an industrial environment where the structures and performance survive an explosion or accident with hazardous substances?
The benefits of simulation are clear. Computer modelling is easy to reproduce with minor changes. It reduces the need to build and test prototypes. Time, effort, and money are saved when the best solutions are discovered already in an early stage of planning.
The tool that normally interests industrial engineers and decision-makers has suddenly become a part of regular citizens’ life. You could almost say that computational fluid dynamics has become popular in 2020.
Even the average Joe wants to know how the microscopic particles in the air we breathe move in the indoor air of shopping centres and supermarkets. In other words: how does mechanical ventilation impact the spreading of COVID-19.
The topic was examined in a joint research project by Aalto University, the Finnish Meteorological Institute, VTT, and the University of Helsinki. It’s a good example of the many possibilities of fluid flow computation. It would be practically impossible to research the phenomenon in real-world circumstances. This kind of a research setting is where fluid flow computation shines.
The simulation results are now helping property owners develop ventilation and the physical structures of their facilities so that exposure would be as small as possible for customers and employees. The modelling results also help authorities provide new safety guidelines for citizens in relation to, for example, safe distances and protecting yourself.
Pinja has executed more than 100 fluid flow computation projects for its customers. Highly developed software, a competent team, and extremely high computing power are needed for execution.
For our customer Finex, we researched the hidden safety risks in an industrial area and helped redesign the area from the strength of the window glass to the placement of ventilation holes. A blast wave modelling revealed that the control room constructions should be stronger to resist a potential explosion blast.
It’s clear that it would be practically impossible to figure these things out without simulation.
