The numerical analysis of system flow based on different types of motor selection and wing design with the help of fume filtration system design

Welding is one of the most preferred manufacturing methods because of being open to continuous development and responding the problems encountered with today's technology. The reason why this method is commonly preferred is that it is quite economical and the consumables are easily obtainable. Besides these advantages, there are several disadvantages that affect the health of the welder. The main health risks result from spreading infrared rays, sparks, molten metal splashes, welding fume and harmful gases during the welding time. In this study, a welding fume filtration system will be designed that eliminates the füme locally. This system which provides local suction in the welding environment is a protection system for making the welder healthier and keeping the work environment safer. The welding fume will be filtered by the flame arrestor, fiber and carbon filter in the system. With the help of this system, the weld will be filtered from its harmful particles and fresh air is provided to the working environment. The construction structure of the study was designed with SOLIDWORKS (CAD) program. Numerical analysis was modeled in 2D by using ANSYS Fluent Program. The propeller was designed as a 5 and 8 wings and assembled in 3 different angels (40°, 50°, 60°). Its analysis was done according to these criteria. With the different motor speeds, the most optimal wing structure was found suitable for the construction.
