What is airfoil turbine? 


Best insight from top research papers

An airfoil turbine is a component used in a turbine engine that consists of an airfoil with an outer wall defining a pressure side and a suction side . The airfoil extends axially between a leading edge and a trailing edge to define a chord-wise direction and also extends radially between a root and a tip to define a span-wise direction . The airfoil may have cooling passages within its interior to improve cooling performance . The airfoil may also include external cavities and cooling holes to enhance cooling efficiency . Additionally, the airfoil may have side walls, a turning space, and internal flow paths to induce swirl and provide a passage for a refrigerant . The airfoil can be designed to discharge evaporative and condensing fluids outwardly into the ambient fluid flowing over it, utilizing the moisture in the air to produce work and power .

What is wind turbine?4 answersA wind turbine is a device used to convert the kinetic energy of wind into electrical energy. It typically consists of a rotor, a generator, and a tower. The rotor is supported by a rotor-supporting assembly and is connected to the generator, which converts the rotational energy of the rotor into electrical energy. The turbine may have a cylindrical design, with a stator surrounding a rotor. The stator includes fixed vanes, while the rotor includes rotor wings. The number of rotor wings may be different from the number of fixed vanes. Wind turbines also require various support systems, such as upright support means and load bearing means, to ensure stability and facilitate movement of components. Additionally, some wind turbines may incorporate damping systems, such as fluids and damping bodies, to dampen oscillations and improve performance.
What is generator for wind turbine?4 answersA generator for a wind turbine is the main component of the electrical equipment used in wind electric installations. It is responsible for generating electrical energy and also performs functions to stabilize and regulate the quality of the generated energy. There are different types of generators used in wind turbines, including permanent magnet generators and axial flux generators. Permanent magnet generators have attracted interest due to their high reliability and long availability, especially in large wind turbines. The design of a permanent magnet generator takes into account factors such as magnetization characteristics, field strength ranges, and the use of light alloys to reduce weight. Axial flux generators, specifically coreless axial flux-switching generators, have been designed for micro wind turbine applications, with a focus on reducing cogging torque and achieving low cut-in speeds. Additionally, an optimized wind turbine emulator has been developed using a DC generator driven by a three-phase induction motor, allowing for simulation and testing of wind turbine scenarios.
What is gas turbine power plant?4 answersA gas turbine power plant is a technology used in the energy sector for propulsion and power generation. It is a type of continuous flow internal combustion engine that converts the chemical energy in fuels like natural gas into mechanical energy. This mechanical energy is then used to rotate turbine blades, which in turn drive generators to produce electricity. Gas turbines are known for their flexibility in load demand following, dynamical behavior, and the ability to work on different fuels with minor design changes. They are used in various applications, including power generation in combined cycle cogeneration plants, where the waste heat from the gas turbine is recovered to generate additional power. Gas turbine efficiency can be improved by optimizing the control system and considering factors such as ambient temperature, relative humidity, compressor pressure ratio, and exhaust gas mass flow rate.
What is a hydro impulse turbine?5 answersA hydro impulse turbine is a type of turbine used in hydropower plants that operates based on the principle of impulse force. It consists of a rotatable turbine wheel with attached buckets, and a nozzle that discharges a jet stream of water towards the turbine wheel. The design of the turbine aims to maximize the efficiency of power generation by optimizing the shape of the buckets, jet, deflectors, and turbine casing. The narrow jet stream thickness and high deflected jet stream angle produced by the non-circular nozzle opening contribute to improved turbine output and efficiency. The turbine utilizes the conversion of pressure energy to high-velocity kinetic energy, which is stored in a helical tube as a half-pressure, half-kinetic energy retaining eddy current. The turbine design also incorporates features such as energy-retaining relief discharge water channels, rotating disc-shaped inward-radial eddy water streams, and energy-retaining water-scattering-preventative ribbed runner blades to minimize noise, maintain regulated flow, and prevent refuse entanglement.
What is the wind for wind turbine?5 answersA wind turbine is a device that harnesses wind kinetic energy to generate electricity. It works by converting the wind's kinetic energy into a useful form of energy, such as mechanical or electrical energy. The wind turbine consists of a base, a rotating shaft, and blades. The base supports the wind turbine and the rotating shaft is inserted into the hollow part of the base, allowing it to rotate. The blades, which are arc-shaped sheets, are connected to the rotating shaft and driven by the wind force to rotate along the central axis. This rotation within the segmented, vertically aligned magnetic fields generates electricity. The wind turbine can be operated at a variable rotor speed, and the output power can be adjusted according to the operating characteristic curve. By selecting a tonality-reduced operating characteristic curve, the excitation of system resonance can be reduced without excluding a rotational speed that excites the system resonance.
What is wind for wind turbine?2 answersWind for wind turbines refers to the kinetic energy of the wind that is harnessed and converted into useful forms of energy, such as mechanical or electrical energy, by wind turbines. Wind turbines work on the principle of converting the wind's kinetic energy into electrical energy. Wind energy is considered one of the cheapest and cleanest sources of renewable energy, and wind turbines play a crucial role in harnessing this energy. There are two basic designs of wind turbines: vertical axis wind turbines (VAWTs) and horizontal axis wind turbines (HAWTs). The efficiency of a wind turbine in extracting power from the wind depends on the dynamic matching between the rotor and the wind stream, which is characterized by the power coefficient (Cp) and the tip speed ratio (λ). Wind turbines can be designed for various applications, including small-scale turbines for powering appliances at home or in moving vehicles.
