Application and Short Description
We developed universal burner for gas fuel as a part of economic domestic boiler as a European Union FP6 project for Western Balkan using the computational simulation. We met the unpredictable problems in timing during the iterative steps when we used the nodes on long distance. Data speed transport between the far distanced computers is a limit factor. The main problem is insufficient RAM in preprocessing and processing. Last analyzing show that the parallelization process can be successful on cluster, or grid configurations. Processes are highly scalable, because partitioning divides the computing sub volume with small overlapping. Our aim is to develop more sophisticate simulation model by computational simulation on stronger computer system. We choose open source OpenFOAM CFD software under Linux for further development. We isolated one small segment of burner and by method of finite volumes we formed the grid of about one million cells, and included effects of fluid dynamics and solver module of chemical reactions in combustion processes. Over the temperature, species properties and pressure difference as input parameters, we have got 3-D dynamics of burning, and various temperature, pressure, velocity field, species and pollutions distribution, etc. Segmented pilot program use about 4 Gb RAM and work in parallel processing with eight microprocessor. At the end of project we expect solution with preprocessing grid of about 4 Gb and after adaptation in processing about 40 Gb during the parallel work on 200-400 processors.
