Abstract:
The present work addresses the thermodynamic optimization of small binary-cycle geothermal power plants. The optimization process and entropy generation minimization analysis were performed to minimize the overall exergy loss of the power plant, and the irreversibilities associated with heat transfer and fluid friction caused by the system components. The effect of the geothermal resource temperature to impact on the cycle power output was studied, and it was found that the maximum cycle power output increases exponentially with the geothermal resource temperature. In addition, an optimal turb

For many decades zirconium alloys have been commonly used in the nuclear power industry as fuel cladding material. Besides their good corrosion resistance and acceptable mechanical properties the main reason for using these alloys is the low neutron absorption.

To meet this requirement a thermodynamic database is useful to support material designers. In this thesis some aspects of the development of a thermodynamic database for zirconium alloys

Abstract:
A thermodynamic cycle simulation of the four-stroke spark-ignition engine was used to determine the effects of variations in engine design and operating parameters on engine performance and emission characteristics. The overall objective was to use the engine cycle simulation to determine the difference between a propane-fuelled and an iso-octane-fuelled engine for the same operating conditions and engine specifications. A comprehensive parametric investigation was conducted to examine the effects of variations in load, speed, combustion duration, spark timing, equivalence ratio, exhaust gas r

Abstract:
La industria de la construcción está fragmentada debido a la gran cantidad de Pequeñas y Medianas Empresas (PYMEs) y la multitud de fases que forman parte de un proyecto. Desde siempre, esta situación ha provocado una serie de problemas en la gestión de proyectos y concretamente en la gestión de los procesos de comunicación e información.<br/><br/>La mayoría de PYMEs a nivel de gestión de proyectos necesitan poder gestionar y compartir los documentos de la empresa. Esto se consigue trasladando las aplicaciones básicas del PC y utilizando un servidor como pueden ser los Sistemas de Gestión Docu

Abstract:
The objective of this thesis is to develop a conceptual design of a computerized environment for detailed design of construction activities associated with projects characterized by significant repetition. High-rise building construction is used as the example of repetitive construction projects. The construction cycle design of a typical floor structure is studied to gain an understanding of the difficulty and complexity involved in the activity design process. Modeling techniques currently used in construction planning, modeling techniques developed in the field of operations research, and

Abstract:
碩士<br>國立成功大學<br>機械工程學系<br>85<br>The population density and the living standard in Taiwan are rising steadily. In addition, most of the energy resources are heavily dependent on the import. The cost of electric power is continuously going up, and the reserve capacity of electric power is gradually drying out during the peak time. Therefore, it is very important for this country to gencrate more electric energy in a better way.  A very efficient cogeneration system called Cheng cycle power system which should be perfectly fit to our electric generation need is analyzed in the present study.

Abstract:
Power plant performance can be assessed by the method of thermodynamic analysis. The goal of this thesis is to perform a thermodynamic analysis on the University of Massachusetts’ Combined Heat and Power (CHP) District Heating System. Energy and exergy analyses are performed based on the first and second laws of thermodynamics for power generation systems that include a 10-MW Solar combustion gas turbine, a 4-MW low pressure steam turbine, a 2-MW high pressure steam turbine, a 100,000 pph heat recovery steam generator (HRSG), three 125,000 pph package boilers, and auxiliary equipment.
