The shortfall and rise in energy deposition and combustion via OpenFOAM

Abstract

In the energy deposition process, a heat source is used to melt a powder or wire as it is being deposited onto the face of a material. While powder provides for greater deposition accuracy, wire appears to be more resource efficient than powder. The procedure involves layering materials and allowing them to harden in a melt pool to create new features. Experiments that explore energy deposition are expensive. As a result, Computational Fluid Dynamics (CFD) may be used to simulate the flame or energy deposition. Fick's law is used to describe the transmission of mass fraction species and energy deposition in this model. Fourier's law is used to calculate the temperature field in the CFD model. For the flow of flame, the Navier-Stokes equations of motion are used. Based on the combustion and energy deposition, this verified CFD model may be used to optimize the operational parameters for regulating the size of the flame and the temperature distribution of the flame. The rise in energy deposition near thin channel and combustion tank is examined in the study. The simulation of the issue is done using the Finite Volume Method (FVM). OpenFOAM is being used in producing the graphical results.
