This paper compares planning results of the electricity and water generation inventory up to year 2030 in the State of Kuwait. Currently, the generation inventory consists of oil and gas fired technologies only. The planning study considers two main cases. The first case, Reference case, examines a generation inventory based on oil and gas fired generation technologies only. The second case exa...

In this paper, the method of rationally determining the system structure and operational strategies is proposed for the energy supply system for a hospital based on the optimization approach. First, energy demands are estimated hourly, daily, and seasonally through one year for the hospital with total floor area of 25,000 m. Second, miscellaneous kinds of equipment are listed up such as refrige...

Gas turbines have become the dominant technology for power generation. They can be quickly assembled and put to service. They are convenient for engine exchange during system overhaul. The emission of NOx, SOx, CO, and particulates are also significantly law as compared to coal fired power plants. However, their maintenance cost is relatively high. The perceived best approach to reduce the cost...

Plug-in hybrid electric vehicles (PHEVs) that are driven and charged in ‘dirty’ power systems, with high penetrations of coal and other polluting generation fuels, may yield higher net emissions than conventional vehicles (CVs). We examine the implications of imposing a constraint on PHEV recharging that forces emissions from PHEVs to be no greater than those from a comparable CV. We use the Te...

The goal of this paper is to compare the amortized cost of electricity from two different types of solar thermal energy technologies with the cost of electricity from a coal-fired power plant utilizing newly developed carbon capture (amine-scrubbing) technology. Coal, natural gas, and nuclear fuels are the dominant sources of electrical energy in the United States. Currently, the primary source...

Nowadays, natural gas conforms to the conditions of environmental protection and renewable energy, which plays a significant role in the future development of mankind. It has made some progress in applying natural gas to the automotive industry. As we all know that the source power of automobile comes from engine, therefore, based on the study on the control algorithm of gas engine, this paper ...

A regenerative organic Rankine cycle (RORC) is modeled and optimized for the use of waste heat recovery from a prime mover (PM). Three PMs including, a diesel engine, a gas engine, and a microturbine are selected in this study. Four refrigerants including isobutane, R123, R134a, and R245fa are selected. The nominal capacity of the PM, PM operating partial load, turbine inlet pressure, condenser...

This paper examines sources and contributions of friction in heavy-duty diesel engines. Current and past work done on the characterization of diesel engine friction will be reviewed. It is also a goal to analyze each component system from a basic mechanics viewpoint highlighting some of the key friction producing phenomena. Different regimes of lubricated friction will be illustrated using a ge...

A Cyber-Physical System (CPS) is defined by its unique characteristics involving both the cyber and physical domains. Their hybrid nature introduces new attack vectors, but also provides an opportunity to design new security defenses. In this paper, we present a new domain-specific security mechanism, FIRED, that leverages physical properties such as inertia of the CPS to improve security. FIRE...
