Finite Element Simulation of the Cooling Process of H-shaped Steel after Circular Nozzle Impinging

Abstract

ANSYS fluent, a finite element numerical simulation software, was used to establish a three-dimensional model of the H-shaped steel web under the impinging impact of nozzle jet. A numerical stimulation analysis was conducted on the mode of water flow and the heat transfer of the H-shaped steel web. In the model, the finite volume method was used to discretize the model into a tetrahedral unstructured grid, the multi-flow VOF model and the achievable K-e model were used to solve the Reynolds average N-S equation, and the numerical solution method adopted the PISO algorithm. This paper aims to calculate the heat transfer performance of the ultra-fast cooling process of the H-shaped steel web under different boundary conditions, as well as explore the influence of impinging time on the distribution of water volume and temperature fields of the web by simulating the cooling process of H-shaped steel web with circular nozzle jet.
