An empirical study on the process of mechanical design

Creator:: Stauffer, Larry A.
Abstract:: An information processing model of the problem-solving performance of mechanical designers is presented for four design tasks: conceptual assembly design, layout component design, detail component design, and catalog selection. These tasks are organized into six kinds of segments called episodes, which describe the goal structure of the designer while performing...

Experimental combustion analysis and development of representative fuel specifications for selected wood and refuse derived fuel pellets from the Pacific Northwest

Creator:: Haluzak, Charles Craig
Abstract:: An experimental biomass combustion facility has been built and established at Oregon State University. The furnace, or Biomass Combustion Unit ( BCU ), uses an augertype fuel feed system, grate-type fuel support with under and over fire air supply. Fourteen pellet species from five States - Alaska, Washington, Oregon, Idaho,...

Off-design analysis and control of a wood-fired combined-cycle power plant

Creator:: Brawn, Robert Charles
Abstract:: This report presents the off-design analysis of various wood-fired combined-cycle power plants using a computer model to simulate plant performance. The combined-cycle systems investigated are characterized by having a woodfueled combustor, an indirect-fired gas turbine, and a Rankine steam cycle. This work was conducted as part of a larger biomass...

Analysis of wood combustion and combustion systems for a combined cycle wood-fired power plant

Creator:: Dadkhah-Nikoo, Abbas
Abstract:: This report presents the study of wood combustion and combustion systems for a combined cycle wood-fired power plant. The power plant consists of a twin air cycle and a single steam cycle. The fuel for this power plant is wood and wood waste with particle size in the range of...

Discrete-time blade pitch control for wind turbine torque regulation with digitally simulated random turbulence excitation

Creator:: Sharif-Razi, Ali-Reza
Abstract:: A time domain simulation model which approximates the three-dimensional velocity fluctuations of wind turbulence has been developed. This model is used in a discrete time control algorithm to regulate the output torque of a wind turbine by changing the pitch angle of the turbine blade. The wind model provides a...

Analysis of ceramic heat exchangers for use in a combined-cycle, wood-fired power plant

Creator:: Ranasinghe, Jatila
Abstract:: This report presents the analysis of ceramic heat exchangers for use in a combined-cycle, wood-fired power plant. The combined-cycle system investigated is characterized by having a wood-fueled combustor, an indirect-fired gas turbine, and a Rankine steam cycle. The direct use of low-grade fuels, such as wood, in present gas turbines...

Thermal and seismic analysis of piping systems using classical methods

Creator:: Nisargand, Arun L.
Abstract:: "Piping Design and Engineering" first published in 1963 by Grinnell, Co. is widely used by engineers to perform approximate thermal stress analysis of high-temperature piping systems. The text consists of numerical constants to calculate end reactions and maximum bending stresses in a variety of piping configurations from known properties of...

Analysis of a wood-fueled trimburner system for use in a combined-cycle, wood-fired power plant

Creator:: Stephenson, Jerry D.
Abstract:: This report investigates the use of wood to fuel a trimburner incorporated in a combined-cycle, biomass-fired power plant. The term "trimburner" applies to a ductburner which is designed to boost the temperature of the air stream entering the gas turbine. The work presented here is part of a larger biomass...

An experimental study of radiative and total heat transfer between a high temperature fluidized bed and an array of immersed tubes

Creator:: Lei, David Hsien-Yu
Abstract:: Experimental data are reported for the time-averaged local radiative and total heat transfer coefficients for both an array of horizontal tubes as well as a single horizontal tube immersed in a large-particle fluidized bed at elevated temperatures. Spatial-averaged heat transfer coefficients computed from the local values, using a simple trapezoidal...

Experimental studies of heat transfer with an array of horizontal tubes immersed in a high-temerature fluidized bed

Creator:: Goshayeshi, Ali
Abstract:: An experimental study is described in which time-average local heat transfer coefficients were obtained for arrays of horizontal tubes immersed in a hot fluidized bed. Spatial-averaged heat transfer coefficients, computed from local values, are also reported. Refractory particles with surface mean diameters of 2.14 mm and 3.23 mm were fluidized...
