Flecs, a Flexible Coupling Shell Application to Fluid-Structure Interaction
Numerical simulations involving multiple, physically different domains can be solved effectively by coupling simulation programs, or solvers. The coordination of the different solvers is commonly handled by a coupling shell. A coupling shell synchronizes the execution of the solvers and handles the transfer of data from one physical domain to another. In this paper, we introduce Flecs, a flexib...
متن کاملEffect of Thermal Environment on Vibration Analysis of Partially Cracked Thin Isotropic Plate Submerged in Fluid
Based on a non classical plate theory, an analytical model is proposed for the first time to analyze free vibration problem of partially cracked thin isotropic submerged plate in the presence of thermal environment. The governing equation for the cracked plate is derived using the Kirchhoff’s thin plate theory and the modified couple stress theory. The crack terms are formulated using simplifie...
متن کاملReduction of the Radiating Sound of a Submerged Finite Cylindrical Shell Structure by Active Vibration Control
In this work, active vibration control of an underwater cylindrical shell structure was investigated, to suppress structural vibration and structure-borne noise in water. Finite element modeling of the submerged cylindrical shell structure was developed, and experimentally evaluated. Modal reduction was conducted to obtain the reduced system equation for the active feedback control algorithm. T...
متن کاملFluid Vibration Induced in T-Junction with Double Side Branches
A T-junction is a fundamental fluid element prevalent in pipe networks of water supplies and power plants. In the present study, a double T-junction was investigated for flow instability and fluid vibration. Both axi-aligned and skewed double T-junctions are examined from viewpoint of flow instability. With single-phase flow in an open-ended double T-junction, fluid vibration is induced in both...
متن کاملParticle-vibration coupling and shell structure of exotic nuclei
We discuss the effects of particle-vibration coupling on the shell structure of nuclei near the neutron drip line by choosing, as examples, 10Be and 24O cores. In particular, we calculate the energy shifts of single-particle neutron states induced by the interaction with collective modes. In the case of the 10Be core, the coupling to 2+ states is responsible, within our model, of narrowing the ...
