The method of manufactured solution (MS) is well known as a verification method of numerical simulation algorithms. In this study, the authors develop a new MS with dynamic interfacial deformation due to a vortex, which is a simplified model of the gas entrainment (GE) behavior in sodium-cooled fast reactors and is necessary for the verification of a high-precision numerical method developed for the simulation of the GE. The MS is considered on an axisymmetric system and radial, circumferential and axial velocities and pressure are formulated to satisfy the continuity equation and the boundary condition on an interface. Preliminary calculations are performed on five meshes with various resolutions and the calculation error decreases with mesh resolution. Such an appropriate result implies the developed MS is a good problem to verify the high-precision numerical method.
