Grinding mechanism of high-temperature nickel-based alloy using FEM-FBM technique

Abstract

The models, simulation, and validation were presented during the last decade over various moving particle investigations with thermal convection and disclosed the challenges as well. The present work provides the simulation and validation of the grinding mechanism of high-temperature nickel-based alloy with single abrasive grain. Several nickel-based alloys provide better performances for temperatures above 1000 °C and those suited for extremely difficult conditions as well. In this study, we simulate and analyze the grinding mechanism of high-temperature nickel-based alloy using single abrasive grain cutting. Using a grinding, it introduces variation in friction coefficient as per the variations of the grinding parameters. The grinding force system of single abrasive grain is designed and simulated to investigate high-temperature nickel-based alloy using various grinding conditions like particle settling modes such as rolling, horizontal, and vertical with thermal convection. The multi-grid finite element fictitious boundary method (FEM-FBM) is used to simulate and study the grinding mechanism of high-temperature nickel-based alloy in terms of fluid-particle sedimentations. The material used for this simulation study is Inconel 718 alloy. The simulation results investigate the various grinding force conditions of high-temperature nickel-based 718 alloys using the dimensional physical parameters and numbers such as Prandtl number and Grashof number. Finally, the simulation results were validated with a conventional FEM model.
