Using Finite Volumes Method in Product Design-From Fan to Surface Cleaning Device

The study highlights the "evolutionary design" processes and the results of the product through the example of a device design at the target of surface cleaning at high buildings. In today's high buildings glass cleaning is carried out manually by the employees with the help of building ropes. During this process, there are frequent situations in which employees are exposed to vital danger due to environmental wind speeds. An innovative suction nozzle design has been developed and implemented using the Computational Fluid Dynamics (CFD) method in order to create a high suction capacity device while adhering to the fan model in operation. Thus, for a cleaning robot that can operate successfully at high environmental wind speeds, a suction hood design has been developed that allows the fans with high suction capacities to generate a high momentum and thus make the vacuuming process healthier on the glass surface. In this context, channel models with different suction mouths according to 3000-4500 rpm capacity fan model have been examined by HAD method. When design decisions were made, form changes were made according to the data obtained from CFD method, optimal product design was realized and productivity was increased. It also tried to emphasize the process-related effects of the evolutionary design approach used alongside the technical output of the product.
