  • Book chapters: 'Wetting film' – Grafiati

    Due to the low wetting angle between molten metal and the filter material, capillary forces drive the melt through the filter. Therefore, the melt velocity through the filter is high. This justifies the usage of potential flow in the branch model. It is shown that molten silicon may be contaminated in …

    The obtained results for square root computation proves that the use of CLZ as an optimization tool outperforms the conventional method by 46.6115 %. Also, an efficient and less complex decoding algorithm using CLZ for variable length prefix code viz., Huffman code is proposed in this paper. ... An LC filter has been designed to improve the ...

    2015-7-1 · A continuously fed consumable solid or tubular (metal cored) electrode used. The molten weld and the arc zone are protected from atmospheric contamination by being submerged under a blanket of granular fusible flux. When molten, the flux becomes conductive, and provides a current path between the electrode and the work Dr. N. RAMACHANDRAN, NITC ...
