The energy performances of both systems were analyzed and compared. The new design boosted the energy efficiency about 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.

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. Skip to main content.

In this paper, a natural gas fired and induction heating furnaces of a forging process were studied. Evaluating thermal environments for sitting and standing posture more.

The operation cost of both systems is a vital argument to be solved. Results are in good agreement with available experimental data. The model is based on the heat balance equation for human body with different types of clothing ensembles, combined with empirical equations defining the sweat rate and mean skin temperature.


In this work, the energy and exergy analysis of a commercial gas turbine, with inlet air cooling, was performed. In the study, the natural convection and radiation losses, the discharge losses and the losses due to kinetic energy were calculated and presented. There are different techniques used for inlet The second law analysis can be used to calculate the system performance based on exergy.

His areas of in I highly recommend this subject to researcher since it is an untouched subject. 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.

The exergy efficiency was calculated to be around Hence, in this study a firm in the steel industry is chosen for case study. The given data were derived from the projection reports, strategic plans, action plans and activity reports of the state authority companies.

İstanbul İklim Şartlarında Rüzgar Ve Güneş Sistemlerinin Modellenmesi Ve Ekserji Analizi

Calculations have been made for four different cases for the regarded gas turbine system. This study is concerned with the energy and exergy efficiency analysis of a novel air heater that operates with induction principle. He leads the Board of University-Industry Collaborations.


Finally, for construction of pump storage systems in Turkey, the importance of incentives and legislations are discussed. Law of Thermodynamics and the thermal losses from the system were calculated during the transient condition. This study represents an experimental and numerical investigation of the enhanced prototypes of the induction air heaters.

Furthermore, exergetic efficiency, exergy destruction rates and improvement potentials were obtained, and the results of the study demonstrated graphically. The general equation of heat conduction was solved analytically in cylindrical coordinates. In this direction, first step should be the monitoring the current energy consumption in any industry.

Thermal EngineeringThermodynamics analizl, and Thermal comfort. The aim of this paper is investigation of the energy and the exergy efficiency augmentation of the new K-1 induction air heater prototype. To achieve the objective, a useful and simple second law based thermo-economic model with instant access to production costs is introduced and generalized.
