“…In CIP-LSM, the governing equations are described and discretized along the generalized curved coordinates (ξ,η,ζ), and the independent variables Q = (T, p, u) T are solved with TCUP (3) - (6) , temperature-based CCUP (7) . In the discretization, the variables Q are collocated at the center of each control volume Ω, where…”

For the prediction of sloshing in the propellant tank of a rocket vehicle, the preliminary investigation was conducted. The flow field in the propellant tank during the ballistic flight of the vehicle was experimentally reproduced with the sub-scale model. The lateral acceleration as large as about 0.8 G was provided with a mechanical exciter and the deformation of the liquid surface in the small vessel was visualized with a high-speed camera. The sloshing phenomena were also simulated with the CFD code, called CIP-LSM. The important features of surface deformation and wave breaking were successfully reproduced in the computation.

“…However, these methods have not sufficiently shown its effectiveness for large‐eddy simulation (LES) of turbulence and supersonic flows and have not been applied for unstructured grids composed of arbitrary polyhedra because it discretizes the advection term of the nonconservation form using a semi‐Lagrangian scheme such as the cubic interpolated propagation (CIP) method. For instance, turbulent flows have not been calculated by the thermo–CIP‐CUP method with LES, and the introduction of artificial viscosity was required to calculate supersonic flow in the work of Himeno and Watanabe .

Pressure‐based unified solver for gas‐liquid two‐phase flows where compressible and incompressible flows coexist

Summary We propose a pressure‐based unified solver for gas‐liquid two‐phase flows where compressible and incompressible flows coexist. Unlike the original thermo–Cubic Interpolated Propagation Combined Unified Procedure (CIP‐CUP) method proposed by Himeno et al (Transactions of the Japan Society of Mechanical Engineers, Series B, 2003), we split the advection term of the governing equations into a conservation part and into the rest. The splitting of advection term has two advantages. One is the high degree of freedom in choosing discretization schemes such as central‐difference schemes, upwind schemes, and Total Variation Diminishing (TVD) schemes. The other is the ease of implementation on unstructured grids. The advantages enable the analyses of various flows such as turbulent and supersonic ones in actual complicated boundaries. Therefore, the solver is useful for practical analyses. The solver was validated on the following test cases: subsonic single‐phase flows, incompressible single‐phase turbulent flows, and incompressible gas‐liquid two‐phase flows. With unstructured grids, we obtained the equivalent results as the ones with structured grids. After the validations, subsonic jet impinging on a water pool was calculated and compared with experimental results. It was confirmed that the calculated results were consistent with the experimental ones.
