A cold model of a rotary holding furnace was studied using water and a kerosene-LIX973N organic mixture which are immiscible. The residence time distribution obtained showed that there was an optimum depth of the upper layer of organic where mixing with the bath fluid was maximised. The use of air bubblers showed that at low air flow rates, the air curtain acted to limit mixing but as the air f...

Cu/Sn/Zn stacked layers were electrodeposited and subsequently annealed in a tube furnace in elemental sulfur and selenium at 570oC. Cyclic voltammogram of Sn-salt in ionic liquid was recorded. Thin films were characterized by inductively coupled plasma-mass spectrometry (ICP-MS), Auger electron spectroscopy (AES) and scanning electron microscopy (SEM). The device was characterized by current-v...

In order to facilely achieve pretreatment and salt-free dyeing of greige knitted cotton fabrics, a combinative scouring, bleaching, and cationization pretreatment of the fabrics is designed in this study. The fabrics are first treated in a bath containing commercial scouring and bleaching agents, and then glycidyltrimethylammonium chloride (GTA) is directly added into the bath to achieve cation...

A glass production furnace requires a considerable amount of energy to allow the correct melting process. In this work, CFD model has been developed in order simulate convective flow movements within molten bath furnace. heat flux profile assigned free surface combustion process, and modelled with thermophysical properties variable temperature based on its chemical composition. The validated by...
