In order to find out the best geometry or structure of the bladeless fan, we have analyzed and simulated the flow and temperature in the fan. The reason to find the best geometry of the fan is to maximize the efficiency of the bladeless fan. There are some doubts about the efficiency of the bladeless fan. We have drawn the model in CAD, Computer Aided Drawing before analysis and simulated a few models and analyzed the air flow with ANSYS fluent program, to check visually and compare the velocity and mass flow. For instance, we simulated the standard case where we use it as a reference for our analysis. The parameters that we amended to see the difference are the size of the fan or the radius of the fan, the angle of the fan and the nozzle distance or the size of the nozzle. Thus, we simulated 6 situations each with one parameter changed. In the standard case of the bladeless fan, the radius of fan is 4.098 cm, the angle is 8 degree and the nozzle distance is 0.11 cm. For the radius, the changed it to 5.159 cm and 3.06 cm respectively. As for the angle, we amended them to 6 degree and 10 degree respectively. Finally, for the nozzle distance, we used 0.25 cm and 0.06 cm. For the radius, the model that showed larger velocity and mass flow is the small fan size model. On the other hand, the model that showed more desirable results is the angle of 10. Furthermore, the nozzle distance that showed higher velocity is 0.06 cm nozzle distance. By using these results, we have combined all 3 parameters for the optimized bladeless fan. After running the simulations, the mass flow for the optimized fan is 0.017119 kg/s and the maximum velocity is 20.2407 m/s. In addition, we used the maximum velocity obtained to calculate the sensible temperature.
