Abstract

Performance of an engineering device are mainly depends on its ability to adapt and functional at the most extreme conditions. This project mainly highlight on the design of wind ventilator turbine with and without tubercles added. The objective of this report is to to compare the CFD analysis result of drag and lift coefficient among three blade design. The blade with 15, 8 and without tubercle was put on a test The geometry of the blade was generate using SOLIDWORK software before transferred to ANSYS software by changing the file to IGES format. The geometry was then edited to satisfy the real situation condition. Mesh was generated and the boundary condition of the model was set to avoid any error occur. The simulation was made using standard k-epsilon model. Inlet velocity of the test section was set for four different values and the calculated solution result of ANSYS was recorded and plotted. The result shows that the blade that having more tubercles are more likely to have a better input on lift coefficient Meanwhile the drag coefficient resulted an increase pattern of graph for all simulation test conducted with different maximum values. Ratio of lift and drag force also be considered in order to compare the best blades design. By using calculation method, it is also shows that the more tubercles present on the blade edge, the higher and consistent the ratio would be which affect the effectiveness of the device.
