“…The final addition of the hydrodynamic calculation with buoyancy was applied in Martin et al [29,30], but the methodology made no enrichment in the approximation of the velocity and pressure fields. It was not until Li et al [31] that XFEM with LSM coupled the Stefan and hydrodynamic problems and considered non-constant density phase changes and buoyancy effects. However, to the author's knowledge, there is no full Navier-Stokes implementation of the coupled problem that is able to simulate phase change at high Reynolds numbers.…”

“…Due to the complex nature of the problem, where the location of phase interfaces varies with time, only a limited number of analytical solutions are available 55 . Numerical techniques are therefore widely used to model the discontinuous temperature gradient field at phase interfaces 56‐60 Two‐phase flows A flow consisting of different phases (see Figure 1C) is commonplace in industrial applications such as oil and gas in pipelines, and water and steam in nuclear reactor cooling systems 61 .…”

“…55 Numerical techniques are therefore widely used to model the discontinuous temperature gradient field at phase interfaces. [56][57][58][59][60] • Two-phase flows A flow consisting of different phases (see Figure 1C) is commonplace in industrial applications such as oil and gas in pipelines, and water and steam in nuclear reactor cooling systems. 61 Since these phases have different properties, the interface between them can result in discontinuous velocity/pressure fields (under a slip condition) and their corresponding gradient fields.…”

“…The jump in pressure is not considered. Recently, Li et al [20] and Martin et al [21] consider the XFEM method to solve two-dimensional solidification problems including natural convection. They use abs-enrichment scheme for the temperature approximation, while the sign-enrichment scheme for the melt velocity and pressure.…”
