description abstractIn this inquiry, we delve into the manner by which disparate orifice configurations exert influence upon the elevation of the jet flame when subjected to an external conflagration, employing empirical simulations. Elaborating upon the empirical dataset, we introduce the derivative of hydraulic diameter alterations and the velocity of material degradation, thereby revising the traditional non-dimensionalized model of flame altitude. The revelations disclose that, across an array of orifice profiles, the conflagration jet within oil-laden apparatus undergoes four discernible phases of evolution, each replete with variable flambeau altitudes. In disparate operational circumstances, the quantified velocity of material degradation during the evolution phase manifests an exponential interrelation with the approximated value of the model. Conversely, the phases of stability and decline adhere to a potency function connection. A quantitative delineation of the pivotal states for each phase of combustion is achieved through the evaluation of the rate of alteration in the velocity of material degradation. Significantly, the pivotal juncture for the proliferation and equilibrium stage is ascertained to be 2 g/s. This scientific inquiry confers invaluable theoretical reinforcement for fire safeguarding and catastrophe evaluation within substations accommodating oil-infused apparatus.
