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...

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 numerical evaluations.

In this evaluation, ANSYS CFD was used for the fluid-particles-structure simulation while the statistical and image processing were made via MATLAB software. The simulation results were verified with the results from an in-house scaled-down model which was fabricated with the ratio of 2:15.
