Microgeração de energia elétrica (Abaixo de 100 kW) utilizando turbina Tesla modificada
An economical electricity generating system is developed, i.e., a boiler and turbine with a capacity ≤ 100 kw, to occupy a niche market where the existing steam systems are not economically viable. A Tesla turbine is used. ...
THEORETICAL AND NUMERICAL ANALYSIS OF EROSION IN STEAM TURBINE BLADES
In the low pressure section of the steam turbines the damages due to the erosion are pronounced becoming remarkable in all the stages, since the generation of water liquid microparticles implies the impact on the blades ...
An Integrated Procedure for the Structural Design of a Composite Rotor-Hydrofoil of a Water Current Turbine (WCT)
This paper shows an integrated structural design optimization of a composite rotor-hydrofoil of a water current turbine by means the finite elements method (FEM), using a Serial/Parallel mixing theory coupled with a ...
Thermoeconomic analysis of a cogeneration system of a university campus
In this paper, a thermoeconomic analysis method based on the First and the Second Law of Thermodynamics and applied to analyse the replacement of an equipment of a cogeneration system is presented. The cogeneration system ...

A Magnus Wind Turbine Power Model Based on Direct Solutions Using the Blade Element Momentum Theory and Symbolic Regression
A model of the power coefficient of a mid-scale Magnus wind turbine using numerical solutions of the Blade Element Momentum Theory and symbolic regression is presented. A direct method is proposed for solving the nonlinear ...
Analysis of the performance of an extraction-condensation steam turbine on a cogeneration system of a Brazilian sugar-alcohol factory
(Natl Technical Univ Athens, 2006-01-01)
In this work a detailed thermodynamic analysis for an extraction-condensation steam turbine capable to drive a 40 MVA electricity generator in a sugar-alcohol factory was carried out. The use of this turbine in the ...
A New Proposal Using a Turbine in the Reactor with a Cavitation System in the Biodiesel Synthesis
The present research investigates the effect of a cavitation system with a turbine in comparison to the vigorous stirring on the process of biodiesel synthesis by the transesterification reaction using oil (triglycerides) ...
