Model-based Slopping Detection in a Top-blown Steel Converter

The most common steel-making process in the world is the Lintz-Donawitz converter. During operation, a slag foam is created to improve the converter performance. Problems arise when the foam level exceeds the height of the vessel and overflows, causing metal loss, process disruption and environmental pollution. The goal of this study is to design a model-based algorithm exploiting real-time pro...

Electrostatics in wind-blown sand.

Wind-blown sand, or "saltation," is an important geological process, and the primary source of atmospheric mineral dust aerosols. Significant discrepancies exist between classical saltation theory and measurements. We show here that these discrepancies can be resolved by the inclusion of sand electrification in a physically based saltation model. Indeed, we find that electric forces enhance the...

effect of bataine and sulphate supplement on wool and milk characteristics and lambs performance in naine ewes

تعداد 20 رأس میش نژاد نائینی 6+-24 ماهه، با میانگین وزن 2/3-+40 کیلوگرم، همراه با 20 رأس بره های آنها در قالب طرح کاملا تصادفی اثر بتائین و مکمل سولفات بر خصوصیات شیر و پشم و عملکرد بره ها بررسی شد. میش ها بطور تصادفی در چهار تیمار قرار گرفتند. تیمارها عبارت بودند از: 1-گروه شاهد 2-بتائین (05/0 درصد ماده خشک) 3-سولفات (24/0 سولفور درصد ماده خشک 4-بتائین هرماه با سولفات. جیره غذائی طبق nrc با مح...

Dynamics of Air-Blown Dimples

A classical problem in fluid mechanics is that of a jet impinging on a solid surface. During the 1960’s, partly driven by applications in the steel industry, the exploration of this field of study shifted towards the interaction between a gas jet and a deformable liquid surface (Figure 1), where often the shape of the deformation and its relation to the balance of forces were studied. This is a...
