Solidification Curve Analysis of Cylindrical Casting by FEM

By Dharmesh Barodiya, M. D. Mahajan, Shaheen Beg Mughal

Abstract: In casting process, molten metal is solidified in mould cavity. Solidification process majorly classify into three different sections: (i) liquefaction (ii) solidify (iii) after solidification. In all three processes, one parameter which is called 'IHTC' (Intermediate Heat Transfer Coefficient), is varies with time. IHTC coefficient depends on shape, size, type of casting etc., so, it is continuously varies with all dependent functions. So, establishment of IHTC value is a very …

Predictability of Equation of State (EoS)-based Gas Hydrate Models for Single and Binary Gas Mixtures

By Jitendra S Sangwai, Prathyusha Mekala

Abstract: The better models are necessary to design and understand the phase behavior of produced trapped natural gas from natural gas hydrates from subsea environments. Most of the models available in an open literature are primarily applicable at relatively low pressure condition thus making their use very limited for gas hydrate reservoir modeling. In order to produce methane from these gas hydrates, it is important to understand the phase behavior through …
