Creator:: Ranasinghe, Jatila
Abstract:: The second law of thermodynamics, through the exergy concept, allows us to quantify and rationally cost the consumption of exergy (irreversibility) used to drive the heat exchange process and the effluent losses of exergy in a heat exchanger For systems with a network of heat exchangers, the exergy concept recognizes...

Creator:: Hamedani, Hooshyar M.
Abstract:: An experimental investigation was carried out to determine the thermodynamics and fluid mechanics of the pipe flow of magnetic fluids. A water-based magnetic fluid was synthesized in the laboratory and its relative viscosity and magnetic properties were determined as a function of temperature. A "thermomagnetic pump" was built and tested...

Creator:: Sitthiphong, Norkun
Abstract:: The object of this research study is to investigate and provide some fundamental information about bed slumping in a partially defluidized bed combustor. Due to the difficulty in making measurements and observations at high temperature, a dynamically similar cold phase fluidized bed was used to model the high temperature case....

Creator:: Fox, Stephen John
Abstract:: This thesis presents thermodynamic evaluations of various biomass-fueled combined-cycle power plants using a computer model developed for simulating such plants. The combined-cycle systems Investigated are characterized by having a wood-fueled combustor, an indirect-fired gas turbine, and a steam cycle. This work was part of a larger biomass energy project at...

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...

Creator:: Ilcewicz, Larry Bert
Abstract:: Wave dispersion and fracture are phenomena that involve. mechanisms triggered at the scale of a material's internal structure. Experiments were performed with a candidate material to judge the hypothesis that wave dispersion measurements can be used to nondestructively predict fracture strength. Wood-based particleboard was chosen as the candidate material because...
