Steam Turbine


Turbine is the generic given to most motor turbomachinery. These are fluid machines, by the using of  thah a fluid passes and it continuously delivers its energy through a paddle or impeller blades.

The turbine is a rotary engine that converts energy into mechanical energy of a stream of water, steam or gas. The basic element of the turbine is the wheel or rotor, with paddles, propellers, blades or buckets placed around its circumference, such that the moving fluid produces a tangential force behind the wheel and spins. This mechanical energy is transferred through a shaft to provide movement of a machine, a compressor, an electric generator or a propeller.

The turbines are made of one or two paddle wheels, known rotor and stator, the first being that, driven by the fluid drag the axis on which the rotational movement is obtained.

So far, the turbine is one of the most efficient engines in the world (about 50%) compared to internal combustion engines and even some electrical. Back in the 20s, some inventors, including one named Thyssen, patented a steam turbine which attributed a thermodynamic efficiency of 31%.

The term turbine is also applied, as the main component, the set of several turbines connected to a generator for producing electricity.

Study In Iran

"We can establish a connection between this university (UNI) and technological universities in my country, to transfer experience and information technology issues and her students to work with us," was the theme that shone during the visit of Ambassador of the Islamic Republic Iran in Nicaragua Mr. Saeid Zare, who met with the authorities of this university.

The diplomat spoke with university officials about the importance of universities for the development of peoples, also showed great interest in the admission process running the UNI for students who wish to pursue their career in this Alma Mater. In this regard the ambassador said, you can establish an exchange of students and teachers at the UNI with colleges of engineering in Iran.

For his part, Rector of UNI, Eng. Nestor Zeledon Gallo said he was very pleased by the opening of diplomatic, to invite them to submit all documentation to the Embassy college and that it can be evaluated to realize these plans.

"For UNI it is very important this collaboration, because this exchange can allow us to update the knowledge in the field of engineering and maintaining academic quality so far enjoyed not only in Nicaragua but also at the level of the Central American region," concluded the Rector.

The Islamic Republic of Iran has a student population of 5 million students, distributed in 2,800 universities, including 2 300 public and 500 private.
