The aim of this article was the development of the gas-dynamic models allowing to calculate the working processes of the gas turbine engine (GTE) in the compressor, in the combustion chamber and in the turbine at the same time. The possibilities of software systems for complex engine workflow modeling are specified. The advantages and disadvantages of the presented methods are specified. The re...

a laboratory stirred tank bioreactor with six single and dual-impeller configurations was tested to obtain the optimum operating conditions for future biological processes. six impeller combinations consisting of three basic impeller types, namely rushton turbine (rt), pitched 4blade (p4b) and pitched 2blade (p2b) downward flow were investigated in 1.77 l bioreactor working volume. power consum...

Abstract—There is a gap at combustor-turbine interface where leakage flow comes out to prevent hot gas ingestion into the gas turbine nozzle platform. The leakage flow protects the nozzle endwall surface from the hot gas coming from combustor exit. For controlling flow’s stream, the gap’s geometry is transformed by changing fillet radius size. During the operation, step configuration is occurre...

To achieve higher efficiency target of the advanced turbine systems, the closed-loop steam cooling scheme is employed to cool the airfoil. It is proven from the experimental results at laboratory working conditions that injecting mist into steam can significantly augment the heat transfer in the turbine blades with several fundamental studies. The mist cooling technique has to be tested at gas ...

the growth of the electrical energy consumption form one side and the bounded available fossil fuel and other limitations from the other side, makes the thermal power plants upgrading as a main demand in the world. decreasing the internal energy consumption, increasing the performance and the output power with the minimum costs are the important targets of the power plants retrofitting. nowaday...

in the current work, different methods for optimization of turbine blade internal cooling are investigated, to achieve higher cyclic efficiency and output power for a typical gas turbine. a simple two-dimensional model of c3x blade is simulated and validated with available experimental data. the optimization process is performed on this model with two different methods. the first method is a po...

and other process equipment in a secure web-based environment and allows users to; • Run your process more efficiently. • Improve your operating margins. • Avoid unnecessary shutdowns. • Improve your maintenance management decisions. GAS TURBINE PERFORMANCE is subject to degradation over time. When gas turbine engines are run, they become fouled with airborne contaminants such as oil, pollen, s...

This paper describes the steps performed by the authors’ company to validate and qualify the introduction of a new fire protection system for heavy-duty gas turbines based on water mist technology. Initially, a finite element model (FEM) of a newly developed 32 MW-class industrial gas turbine for mechanical drive and power generation was generated to simulate gas turbine (GT) casings deformatio...

This study proposed a model-based robust fault detection (RFD) method using soft computing techniques. Robust detection of the possible realistic incipient faults of an industrial gas turbine engine in steady-state conditions is mainly centered. For residual generation a bank of Multi-Layer perceptron (MLP) models, is used, Moreover, in fault detection phase, a passive approach based on Modelli...

The World Wide Web has emerged as an effective mechanism for distributing educational material to students beyond the bounds of the classroom. The introduction of mobile code, such as Java applets, combined with the pervasiveness of the World Wide Web, present the potential to significantly enhance the development and distribution of educational software. This paper illustrates the design and ...
