Résumé

MaranStable is a software to perform three-dimensional linear stability analyses of steady two-dimensional non-isothermal multiphase flows in canonical geometries. Different approximations to the Navier–Stokes equations can be selected, which are discretized by finite volumes on a staggered grid. The stability of the basic flow, obtained by Newton—Raphson iteration, is computed by solving the linearized three-dimensional perturbation equations using normal modes. All calculations are based on Matlab and make extensive use of the already parallelized backslash and eigs operators, and the graphical user interface eases the access to MaranStable.

Stability of thermocapillary flow in liquid bridges fully coupled to the gas phase

Article dans une revue avec comité de lecture

STOJANOVIĆ, Mario; ROMANO, Francesco; KUHLMANN, Hendrik C. (Cambridge University Press (CUP), 2022-09)

The linear stability of the axisymmetric steady thermocapillary flow in a liquid bridge made from 2 cSt silicone oil (Prandtl number 28) is investigated numerically in the framework of the Boussinesq approximation. The ...
Instability of axisymmetric flow in thermocapillary liquid bridges: Kinetic and thermal energy budgets for two-phase flow with temperature-dependent material properties

Article dans une revue avec comité de lecture

STOJANOVIĆ, Mario; ROMANO, Francesco; KUHLMANN, Hendrik C. (Cambridge University Press (CUP), 2023-07)

In numerical linear stability investigations, the rates of change of the kinetic and thermal energy of the perturbation flow are often used to identify the dominant mechanisms by which kinetic or thermal energy is exchanged ...
Coherent Particle Structures in High-Prandtl-Number Liquid Bridges

BARMAK, Ilya; ROMANO, Francesco; KANNAN, Parvathy Kunchi; KUHLMANN, Hendrik C. (Springer Science and Business Media LLC, 2021-02)

Clustering of small rigid spherical particles into particle accumulation structures (PAS) is studied numerically for a high-Prandtl-number (Pr = 68) thermocapillary liquid bridge. The one-way-coupling approach is used for ...
Attractors for the motion of a finite-size particle in a cuboidal lid-driven cavity

Article dans une revue avec comité de lecture

WU, Haotian; ROMANO, Francesco; KUHLMANN, Hendrik C. (Cambridge University Press (CUP), 2023-01)

The motion of a finite-size particle in the cuboidal lid-driven cavity flow is investigated experimentally for Reynolds numbers 100 and 200 for which the flow is steady. These steady three-dimensional flows exhibit chaotic ...
Stokesian motion of a spherical particle near a right corner made by tangentially moving walls

Article dans une revue avec comité de lecture

ROMANO, Francesco; DES BOSCS, Pierre-Emmanuel; KUHLMANN, Hendrik C. (Cambridge University Press (CUP), 2021-09)

The slow motion of a small buoyant sphere near a right dihedral corner made by tangentially sliding walls is investigated. Under creeping-flow conditions the force and torque on the sphere can be decomposed into eleven ...
