1. Modelling and Simulation of Turbulent Gas-Solid Flows applied to Fluidization
Sammanfattning : Modelling of gas-solid suspensions has been studied with emphasis on suitable closure laws. A study of characteristic time scales and energy dissipation mechanisms is made for the case of a simple shear flow. Applications of the modelling are presented in the form of simulation and validation of experiments in fluidized beds. LÄS MER
2. Numerical study of dynamics of mass-emitting particles in multi-phase flow
Sammanfattning : Suspended particles can be found in wide range of industrial applications such as food industry, mining industry and energy conversion processes. Depending on flow cases which particles are involved, different dynamics and motions are expected from suspended particles. LÄS MER
3. Fuel Mixing in Gas-Solid Fluidized Beds: A Computational and Experimental Study
Sammanfattning : Fluidized bed technology has been commercially applied over severaldecades. However there is still a lack of knowledge that can provide adetailed understanding of the combustion process in fluidized-bed furnaces. LÄS MER
4. A novel solar-driven system for two-step conversion of CO2 with ceria-based catalysts
Sammanfattning : Global warming is an unequivocal fact proved by the persistent rise of the average temperature of the earth. IPCC reported that scientists were more than 90 % certain that most of the global warming was caused by increasing concentrations of greenhouse gases (GHG) produced by human activities. LÄS MER
5. Experimental study of a Volatiles Distributor for Improving the Cross-sectional Gas Distribution in Fluidized Beds
Sammanfattning : Chemical looping combustion (CLC) is a promising carbon capture technology due to its inherent CO2 separation. Significant progress has been made in CLC of solid fuels in recent years. LÄS MER
