1.2 The ideal gas turbine cycle To start examing a gas turbine in detail, we make a few simplifications. By doing this, we wind up with the ideal gas turbine. How do we analyze such a turbine? 1.2.1 Examining the cycle Let's examine the thermodynamic process in an ideal gas turbine. The cycle that is present is known as the Joule-Brayton cycle.

proportion of power plants with gas turbines, i.e., open-cycle and combined cycle (combining gas and steam turbines) was around 54% of total fossil fuel-fired power plants.

regulated turbines can change the pitch angle of the blades, to optimise the performance for each wind speed, the stall-regulated turbines are much simpler and rely only on the aerodynamics of the airfoils. This increases the complexity of the airfoil design. First of all, the airfoils of stall-regulated turbines work

Hydraulic turbines are basically classified in two groups; impulse and reaction turbines. Impulse turbines work based on the momentum principle. Water hits the runner blades in the form of a water jet and this impact causes a force on the runner, which causes the runner to turn [8]. Pelton turbine is an example of impulse turbines.

two common classes of HK turbines are axial-flow turbines, in which the rotor shaft is oriented parallel to the water current, and cross-flow turbines, in which the rotor shaft is oriented perpendicular to the water current. The shaft of cross-flow turbines can be oriented either vertically or horizontally. Both of these HK turbine classes can be

3.Types Of Wind Turbines There are two types of wind turbines. One is Vertical axis wind turbines and the other is horizontal axis wind turbines. We also know that there is sufficient wind to satisfy much of humanity's energy requirements - if it could be gathered effectively and on a large scale.

Used wind turbines are purchased by a variety of companies including traders, operators, developers, and engineering companies. Those who purchase used wind turbines may wish to sell the used wind turbine, use it, refurbish it, or remanufacture it. Trading websites give an indication of who buys and sells used wind turbines.

However, offshore turbines still have some disadvantages, for example expensive maintenance due to difficulties with logistics and accessing the turbines. This is especially the case when the weather is harsh.
