DEVELOPMENT OF RESPONSIVE WEB-BASED AIR CLEANING SYSTEM SIMULATION PROGRAM BASED ON OPENFOAM

In Korea, the problem of fine dust is a very big social issue. Korean government has set a goal to improve the country’s air quality to levels equivalent to those of European countries in 10 years. At the lower level, many attempts have been made to dispose fine dust and indoor pollutants by arranging air cleaners in many places. However, it is difficult for the public to know how pollutants are removed. But if the fluid flow analysis can be performed intuitively and the results can be seen easily, the public can indirectly experience how pollutants are being removed. KISTI has developed a responsive web-based air cleaning system simulation program for this purpose. In this program, you can select a room based on 18 templates of general Korean room structure. And this program provides the function to place three commercial air cleaner models at desired positions. It also provides an interface to perform analysis by simply adjusting the flow rate and room size. On the solver side, it provides the option to perform steady-state analysis by solving the scalar transport equation solely based on flow field analysed by ‘simpleFoam’ or to perform transient analysis by performing 'pimpleSpeciesFoam' which is a combination of ‘pimpleFoam’ and species transport equation. Finally, job scheduler developed based on ‘Son of Grid Engine’ can be used to send job queue to perform analysis and users can check the results in real-time.
