The are several ways to increase the aerodynamic performance of an airfoil, one of which is adding a section behind the airfoil which commonly called a flap. Flap functions to control aerodynamic performance. The addition of a flap to an airfoil will create a gap beteen the airfoil body and the flap, it will certainly afferct aerodynamic performance.The gap between the flap and the body…
Airfoil is a cross-sectional form that can result in lift force or aerodynamic effects when passing through an airflow. An understanding of crustaristic aerodynamics includes lift efficiency, drag coefficient and Cl/Cd ratio. In this study numerically investigated different types of airfoils to improve the efficiency of wind turbines used in low-speed wind regions. One method of airfo…
Many business actors, especially business people in the field of confection that does not pay attention to the tools used workers, especially the use of seats that do not fit the dimensions of the body workers so it is not ergonomic for workers who wear them. Whereas the use of ergonomic work tools is very repentant for workers and as business owners because it can increase and comfort the valu…
Abstract- In a wide scope of a network, it cannot be denied that the number of nodes on the network will increase. This will cause a decrease in the performance of the routing protocol used. So, it is necessary to do research to determine the performance of the routing protocols used. Multiprotocol Label Switching or commonly abbreviated as MPLS is one method that can be used in tuning networks…
One of the process of the development of the car is in the production of the body, the development is intended to look for a more aerodynamic body so that the body gets smaller resistance. This innovation is certainly developed to follow the electric car competitions are classed both nationally and internationally. In this research, aerodynamic analysis on the surface of the electric car body …
