Evaluation of the performance of granular fertilizer boom sprayer through computational fluid-particles-dynamid CFD simulation and scaled-down model analysis

Malaysian Agricultural Research and Development Institute (MARDI) had bought two Japanese made granular fertilizer boom sprayers to test it on Malaysia’s Paddy field. In order to confirm the local feasibility of this fertilizer applicator, they had called UTHM researchers for proper experimental and...
