The paper presents a multiphase mathematical model of the AISI 316L stainless steel point heating and melting in the ultrasonic field and its numerical implementation by the finite volume method in the ANSYS Fluent software package. To apply volumetric heat sources and external forces acting on the melt pool, original algorithms based on the user-defined function in the C language are introduced. The paper provides description of the method for using ultrasonic vibrations in the computational domain. It analyzes the ultrasonic vibrations influence on the melt pool flow, width, depth and volume in relation to the numerical experiment with the same parameters, but without the ultrasound. The mathematical model was verified by a full-scale experiment and confirmed qualitative and quantitative characteristics of the ultrasound effect on formation of the melt pool.
