1. Electrothermal Simulation in a Concurrent Waveform Relaxation Based Circuit Simulator
Sammanfattning : The main purpose of this work is to study methods to simulate electro-thermal effects in integrated circuits using CONCISE a waveform relaxation based circuit simulator. WR is a method that is suitable to run on a multi-computer with state of the art computing power. Especially CMOS VLSI circuits have been simulated successfully with WR. LÄS MER
2. Comfort Climate Evaluation with Thermal Manikin Methods and Computer Simulation Models
Sammanfattning : Increasing concern about energy consumption and thesimultaneous need for an acceptable thermal environment makesit necessary to estimate in advance what effect differentthermal factors will have on the occupants. Temperaturemeasurements alone do not account for all climate effects onthe human body and especially not for local effects ofconvection and radiation. LÄS MER
3. Modelling and Simulation of Thermal Radiation in Biomass Combustion
Sammanfattning : This thesis presents numerical investigations and simulations of fixed bed combustion of wood, models for predicting thermal radiative properties of particles and gases related to the combustion of wood, and a review of heat load calculations in gas turbines. All subjects have a common factor in thermal radiation. LÄS MER
4. NOUR - Daylighting and thermal effects of windows in desert houses
Sammanfattning : This study is on a combined effect of window, the daylighting and the thermal effects, in desert houses. It is comprised of two complementary studies. In the introduction a historical review on the development of use daylight has been carried out in order to place the case study in a historical perspective. LÄS MER
5. Investigations of the Kinetics of Reduction and Reduction/Carburization of NiO-WO3 Precursors
Sammanfattning : Kinetic studies of reduction of the mixtures of NiO and WO3 having different Ni/(Ni+W) molar ratios in flowing hydrogen gas were investigated by means of Thermo Gravimetric Analysis (TGA), Fluidized Bed (FB) technique as well as Thermal diffusivity measurements under isothermal conditions. In the case of TGA, the reaction progress was monitored by mass loss, while evolved gas analysis by a gas chromatograph was the indicator of the reaction progress in the case of FB. LÄS MER
