【 摘 要 】

Optimization of boom sprayer collecting plate angle is a tedious procedure if it is done fully experimental. This paper demonstrates that the optimization process is more practical by simulation analysis validate through logical reflection of particles. This study is carrying out through simulating the distribution parts of the boom sprayer by using the commercial software, ANSYS. The multiphysics capabilities of ANSYS enable ANSYS to carrying out this simulation. The simulation is carrying out by manipulating the angle of the collecting plate, 32o, 60o,90oand 120oof the boom sprayer to find the optimum range of angle that will produce a good distribution for different sizes of the granular fertilizers and air velocity of the blower. The constant variables in this simulation are the atmospheric pressure of 1 atm and the particles size of Potassium K is 1mm. There are 60 per cent of the images produce by ANSYS, through observing the number of stream lines and the angle of distribution show that the optimum angle is between 32oto 60o. For further study, in order to increase the accuracy, the simulation is further validate through experiment. It is preferred to carry up the experiment through scaled down model without causing any changes to the current design and in order to be carrying out in the lab.
