Computational simulation of steam flow and heat transfer in power plant condensers on the basis of the threedimensional mathematical model for the flow through porous media is presented. In order to solve the mathematical model of steam flow and heat transfer in power plant condensers, the Streamline Upwind Petrov-Galerkin finite element method is applied. By comparison of the results of simula...

Thermal recovery involves well-known processes such as steam injection (cyclic steam stimulation, steam drive, and steam-assisted gravity drainage), in situ combustion, and a more recent technique that consists of heating the reservoir with electrical energy. When high frequency is used for heating, it is called electromagnetic (EM) heating. The applications of EM heating for heavy-oil reservoi...

This work presents a comparison study between the state-space and polynomial methods for the design of the robust governor for load frequency control of steam turbine power systems. The robust governor is synthesized using the two approaches and the comparison is extended to include time and frequency domains performance, controller order, and uncertainty representation, weighting filters, opti...

Solar parabolic concentrating collectors are widely and efficiently used in electrical generation. They were experimentally validated in worldwide pioneer plants. SEGS-VI 30 MW solar power plant built in southern California is one of these plants that was commissioned many years ago. In this work a possibility of installing such plant in Makkah, 21.4 °N located in moderate latitudes is studied....

The helical steam generator is connected to an HTGR-type nuclear reactor called PeLUIt-40 for production. Steam used generate electricity and hydrogen. A once-through tube bundle was employed because of its ability endure mechanical stress due thermal expansion, high resistance flow-induced vibrations, better performance compared a straight one. To produce the targeted steam, design analysis ne...

Properties of heat-treated wood have been studied extensively in recent years. However, study on wood that has been treated in pressurized steam is limited, as most wood heat treatments are carried out in atmospheric steam. The main purpose of this study was to explore the influence of steam pressure on chemical changes of heat-treated wood. Wet chemical analysis, elemental analysis, and FTIR a...

This work describes two different configurations of syngas production processes using a combination of steam methane reforming (SMR) and dry reforming of methane (DRM). The ideal SMR+DRM process ensures the maximum product yield, the heat-integrated SMR+DRM process fulfills the maximum heat recovery, and the stand-alone SMR+DRM process effectively suppress net CO2 emissions. Through kinetic mod...
