  • utility theory for evaluation of Optimal Process Condition of saw a multi response optimization approach
    INTERNATIONAL CONFERENCE ON ADVANCES IN MATERIALS AND PROCESSING TECHNOLOGIES (AMPT2010), 2011
    Co-Authors: Saurav Datta, Ajay Biswas, Swapan Bhaumik, Gautam Majumdar
    Abstract:

    Multi‐objective optimization problem has been solved in order to estimate an Optimal Process environment consisting of Optimal parametric combination to achieve desired quality indicators (related to bead geometry) of submerged arc weld of mild steel. The quality indicators selected in the study were bead height, penetration depth, bead width and percentage dilution. Taguchi method followed by utility concept has been adopted to evaluate the Optimal Process Condition achieving multiple objective requirements of the desired quality weld.

  • experimental study on catalytic effect of biomass pyrolysis volatile over nickel catalyst supported by waste iron slag
    International Journal of Energy Research, 2017
    Co-Authors: Haimiao Yu, Yalan Shen, Dezhen Chen
    Abstract:

    Summary The study aims to analyze catalytic tar destruction, evaluate the activity of the Ni-based catalyst supported by waste iron slag, and obtain clean pyrolysis syngas. The effects of different nickel loadings, catalytic temperatures, and catalyst calcination temperatures on volatile were investigated in order to determine the Optimal Process Condition. The analysis results showed that the iron slag Ni-based catalyst had a relatively low specific surface area. However, it showed an excellent resistance performance to the coke deposition and displayed the high tar removal ability. Moreover, the tar conversion and the yield of syngas were significantly affected by nickel loadings. When the nickel loading reached 3%, the tar dew point was decreased by nearly 100 °C and the tar conversion reached 94.84%. The favorable reaction temperature was about 800 °C based on the consideration of energy consumption and the catalytic performance. Calcination temperature affected tar yield and syngas yield. The application of iron slag in nickel catalyst realized the reutilization of waste materials, indicating significant practical values. Copyright © 2017 John Wiley & Sons, Ltd.

  • multi response optimization of Process parameters in friction stir welded am20 magnesium alloy by taguchi grey relational analysis
    Journal of Magnesium and Alloys, 2015
    Co-Authors: Prakash Kumar Sahu
    Abstract:

    Abstract The purpose of this paper is to optimize the Process parameter to get the better mechanical properties of friction stir welded AM20 magnesium alloy using Taguchi Grey relational analysis (GRA). The considered Process parameters are welding speed, tool rotation speed, shoulder diameter and plunging depth. The experiments were carried out by using Taguchi's L18 factorial design of experiment. The Processes parameters were optimized and ranked the parameters based on the GRA. The percentage influence of each Process parameter on the weld quality was also quantified. A validation experimental run was conducted using Optimal Process Condition, which was obtained from the analysis, to show the improvement in mechanical properties of the joint. This study also shows the feasibility of the GRA with Taguchi technique for improvement in welding quality of magnesium alloy.
