In continuous casting, molten steel is fed from the tundish into mold through immersion nozzle. nozzle, inclusions mainly composed of alumina present in adhere and accumulate, it causes limitation castings. To prevent nozzle clogging, Ar gas blown However, bubbles flow along with become trapped solidifying shell, causing bubbling defects slab. suppress defects, effective to keep away solidifica...

The effect of the nozzle radial position on both mixing time and slag eye due to bottom gas injection in metallurgical ladles was investigated using physical mathematical modelling. Previous research has extensively effects time, however, few available results with respect ladle indicate contradictory results. To identify optimum area a systematic investigation been carried out. A water model g...

Expansion work recovery by two-phase ejector is known to be beneficial to vapor compression cycle performance. However, one of the biggest challenges with ejector vapor compression cycle is that the ejector cycle performance is sensitive to working condition changes which are common in real world applications. Different working conditions require different ejector geometries to achieve maximum ...
