| چکیده انگلیسی مقاله |
Grasshoppers and locusts are one of the most dangerous and harm full plagues for crops that in each swarm can destroy 35000 people’s food. Grasshoppers and locusts swarm control in different ways. In this study, some grasshopper aerodynamic properties in the wind tunnel have been investigated for the design and manufacture of a locust collection machine. For this purpose, some dead and live grasshopper with grasshopper maquettes were placed in a wind tunnel. Also, a grasshopper in ANSYS software was modeled and analyzed by CFD analysis and extracted velocity, static, and dynamic pressure. According to the experiments that have been done, live grasshoppers were suspended at 6.3 m s -1 wind velocity and in the ANSYS model, the drag force of grasshopper for a throw or suction grasshopper in 6.5 m s -1 was calculated with contours that obtained. |
