11. On some positive effects of swirling flow for the continuous cast mould billets
Sammanfattning : Continuous caster moulds are the last and most important stage in the steelmaking process, where inclusions can either be generated or removed. With increasing casting speed using conventional immersion nozzles critical problems, such as unstable bulk mould flow have been noticed. LÄS MER
12. Large Eddy Simulation of Swirling Reacting Flows
Sammanfattning : The combustion of fossil fuels remains a key technology as these fuels are the main source of energy in the foreseeable future. Heat released in combustion is often accompanied by emission of undesired soot, CO and NOx pollutants. LÄS MER
13. Experimental study of turbulent flows through pipe bends
Sammanfattning : This thesis deals with turbulent flows in 90 degree curved pipes of circular cross-section. The flow cases investigated experimentally are turbulent flow with and without an additional motion, swirling or pulsating, superposed on the primary flow. LÄS MER
14. Numerical modelling of swirling drying flow
Sammanfattning : Waste hydrochloric acid (HCl) from the pickling process at SSAB EMEA in Borl¨ange, Sweden, is regenerated using a technique called spray roasting where waste HCl is sprayed into a hot reactor through four spray nozzles at the top of the reactor. The regeneration (drying) process is driven by four natural gas burners placed symmetrically along the periphery of the reactor and causes the water in the waste acid droplets to evaporate. LÄS MER
15. Analytical and Numerical Studies of Internal Swirling Flows
Sammanfattning : Swirling flows are common in technical applications, e.g. turbines, pumps, fans, compressors and combustors. LÄS MER
