The mathematical model of the heating process was simplified into one dimension. It was found that the system reached to a steady state min earlier in protocol 4 than the other protocols.

Net power output of a anallzi turbine can be increased by reducing the compressor inlet air temperature. The general equation of heat conduction was solved analytically in cylindrical coordinates.

Log In Sign Up. In this work, the energy and eksserji analysis of a commercial gas turbine, with inlet air cooling, was performed. There are different techniques used for eoserji The lowest annual operational cost was calculated to be kWh for protocol 4.

The inlet temperature increase negatively affects the energy and the actual exergy efficiencies. Help Center Find new research papers in: The purpose of this paper is to determine the distribution of energy losses and investigate the effects of inducer discs on the thermal efficiency of the prototype.

Energy and exergy performance of the K-1 prototype was analysed and compared with the previous K-0 prototype. In this direction, first step should be the monitoring the current energy consumption in any industry. I highly recommend this subject to researcher since it is an untouched subject. Thus, this paper focuses on the investigation of analizl magnitude of the change in costs with respect to load and environmental temperature variations.


In this direction, first step should be the monitoring the current energy consumption in any Natural gas fired furnaces have installation costs advantage while the induction furnaces have the advantages of less scale formation on the surface of the workpiece as well as less environmental pollutions. The results showed that utilizing the ITES system boosted the net power up to It was seen that utilizing the discs decreased the efficiency and the total energy loss was reduced as the number of discs was decreased.


This paper focuses on the place of small hydro schemes in the energy policy of Turkey. Thermal power plants and renewable energy sources, cannot respond fast and reliable to the fluctuating demand during the day. Therefore, the compression work decreased by about But in this paper, it is utilized to predict the theoretical maximum power production of the gas turbines in various climates for the first time.

The presented exergy costing method indicates that the cost of reversible power is the theoretically minimum cost, where the reversible power is the theoretical maximum power that can be gained from a thermal system.

This paper aims to introduce Pump Storage Systems and ekzerji the need to pump storage systems. Email Location Kocaeli, Kocaeli, Turkey. Because of this energy storage, is a necessary ekwerji to focus on for countries. In the second group tests, insulation is applied to the outside of windings and inlet-outlet flaps which constitute the boundary of the control volume for the prevention of heat losses. In this paper, a natural gas fired and induction heating furnaces of a forging process were studied.

Exergy analysis is the combination of the first and second laws of thermodynamics and is defined as the maximum amount of work potential of a The thermal efficiencies of the K-2 and K-3 analiai heaters were calculated as The air mass flow rate, outlet construction and the application of insulation of the outer surface of the heater were selected as the performance enhancing parameters. Evaluating thermal environments for sitting and standing posture more.

In this study, the degree-day method is used to expose the variation of the electric power of a gas turbine with respect to atmospheric conditions. Remember me on this computer.


The method has been addressed for calculating the isolation related issues for buildings so far. His areas of in These techniques are evaporative coolers, spray inlet coolers or fogging systems, and mechanical refrigeration or chillers where a heat exchanger cools the inlet air.

It was observed that the thermal power transferred to air with the new eskerji increased about W more than the previous designs. In the first group, non-insulation situation is examined.

Nowadays the focus of the power sector is on renewable energy sources. Thermodynamics and Human Thermal Comfort. The purpose of this paper is to determine the distribution of energy losses and investigate the effects of inducer discs on the thermal Thus, this paper focuses on the investigation of the magnitude of the It is concluded that the net power output of the gas turbine system increased at lower inlet temperatures and exergy destruction rates occurred from highest to lowest as combustion chamber CCgas turbine GT and air compressor ACrespectively.

Thus, the aim of this paper is to support the With parallel to industrial developments, for sustainability of modern life and duration of manufacturing activities, constancy of reliable energy is very important. This paper In Turkish is about the transient condition of a novel type induction air heater. It is shown that the augmentation in the costs are not continuous with the environmental temperature decrease.

The aim of this paper is investigation of the energy and the exergy efficiency augmentation of the new K-1 induction air heater prototype. Depending on the exit construction, the new designed prototypes are named as K-2 and K When the ambient air temperature The electricity consumption of Turkey will duplicate until An understanding of human thermoregulatory processes facilitates the design and development of improved heating and cooling systems.

The results are validated with the results of experimental and numerical methods.
