In the medium air speed wind tunnels where wind speed ranges from 1.5 – 40m/s, several types of wind tunnels can be applied. At first, an open suction type wind tunnel can have a large test section with high contraction ratio [3]. This type of wind tunnel has a large inlet area to take motionless air to the test section. Air filters can be installed before the inlet to prevent any dust from

A wind tunnel is a key instrument used by Aerospace engineers to accurately measure the aerodynamic forces and moment on an aircraft model. The aerodynamic forces and moments that the model experience then can be compared to the real-life conditions that an aircraft experiences in real-time. An important in tool that allows us to find these different force is the L.A. Comp wind tunnel’s pyramidal balance. This kind of balance allows aerospace engineers to measure all the force: lift, drag, and side
velocity for two points that lie on the same single streamline. [1] P_1/(ρ_air g)+(V_1^2)/2g+Z_1=P_∞/(ρ_air g)+(V_∞^2)/2g+Z_2 [Eq. 1] As height will remain constant in a wind tunnel experiment, so gravitational force is eliminated. P_1+(ρ_air V_1^2)/2=P_∞+(ρ_air V_∞^2)/2 The velocity of fluid becomes zero at stagnation point when the pressure tapping 1 is at ∅=0, as the surface of the cylinder is now perpendicular to the

continuing to use fossil fuel as a source of energy. In addition to this, once the fossil fuels have all been used up, there is no chance of obtaining more. There are many types of alternative energy sources in the world that a renewable and may not be harmful to the environment. In addition to this, alternative energy sources have to ability to power large corporations as well as small businesses around the globe. Alternative energy
What is Soil Erosion, Types of Soil Erosion, Causes of Soil Erosion Soil erosion is a naturally occurring process in which the top layer of the soil washes away that affects all landforms which can occur due to heavy rains, cyclone, typhoons, hurricanes, twisters, animals, human activities etc. In agriculture, soil erosion denotes to the wearing away of a field 's topsoil by the natural physical forces of water and wind) or through forces associated with farming activities such as tillage. In Erosion
involved testing three wing designs in a wind tunnel. First, the wind tunnel was turned on with nothing inside and the flow velocity was recorded. Then, the first airfoil, a pre-built standard NACA 0024, was tested. It was put in the wind tunnel in the 0° slot on the Kelvin Lift & Drag Balance arm and locked in place. The balance was then calibrated so that the LIFT value read zero, and the wind tunnel was turned on to its high setting. Once the wind tunnel reached its maximum speed of approximately
As the fear of climate change escalades, more and more people are looking to sustainable energy. This means the race is on for companies to build cars with better gas mileage, products that use less energy, and water saving technologies. Sustainable technology is becoming a massive industry which is why United Arab Emirates, or UAE, wants to get involved. In true UAE fashion their contribution is Masdar City it the world 's first fully sustainable, zero carbon, zero waste city. Masdar City
The aerodynamic performances of a wind turbine with airfoil Type Turbosail blades based on the lifting line model Abstract One of attracting concepts has been the use of Turbosail principle to produce lift from fixed cylinders in various engineering applications. With emerging innovative Turbosail type wind turbine technology, it is important to determine power performance and characteristics of such generators as correctly as possible. The objective of this project paper is to develop an efficient
