Minisymposium 2
"Computational Methods on Fluid-Structure Dynamics for Multiscale Problems"

More Info »

Recent advances in computational mechanics, fluid dynamics and multiscale modelling have allowed for efficient, robust and realistic simulation of nonlinear fluid-structure interaction and multi-fluids systems. This is mainly contributed to new generation of high-performance computational tools and the development of suitable algorithms capable of handling complex nonlinear phenomena. The study of these phenomena requires cross-disciplinary analysis while challenges on developing accurate and reliable models are often associated with the complexity of the system’s dynamics, domain geometry, multi-scale character of physical problem, inherent heterogeneous nature of multiphase fluids, and computational cost for detailed simulations.

The main aim of this mini-symposium is to constitute a forum for idea exchange and knowledge dissemination concerning the latest research developments on cutting-edge technologies for multi-scale and multi-physics methods embedded in computational fluid-structure dynamics.

This mini-symposium will cover fundamental and applied research areas on topics including but not limited to:

  • Multiscale modelling for computational fluid dynamics (CFD);

  • Finite element and control volume element methods (FEM / CVFEM);

  • Advances in continuous or discrete numerical methods for fluid-structure interaction;

  • Porous and poroelastic medium flow;

  • Coupling models for multi-physics problems;

  • Numerical algorithms and optimization techniques for large scale simulations;

Contributions pertaining to the implementation of such methods on real-life applications, such as wind loading vibrations, microseismicity, and hydraulic fracturing are most welcomed.

Cracks in the shafts are critical factor, as they are difficult to detect during operation. Operatives and maintenance personnel of critical plant machinery are particularly interested in early detection of symptoms that can lead to in-service failure of shafts. Many researchers have developed new diagnostic techniques, in order to detect cracks in shaft-rotor system is, therefore, highly essential to avoid catastrophic failure. Vibration signals used as a diagnostic tool for smooth functioning and to avoid an undue stoppage. This paper incorporates experimental and numerical investigation of effect of crack in a shaft, on vibration amplitude levels, frequency spectrum and natural frequency. The experimental setup is developed to study the effect of crack on vibration amplitude. The vibration signals are measured with the help state-of-the-art two channel CEMB N500 FFT analyzer. ANSYS 14 is used to modal analysis for finding theoretical natural frequencies. Impact Hammer Testing is carried out with the help of DEWE-soft 43 platform along with data acquisition system and electronic instrumentation for finding experimental natural frequencies of a system. The results of analysis show that, vibration analysis can be used as a tool to detect crack in shaft, before they cause any failure.

Keywords: Vibration of shaft, Crack, Frequency spectrum, FFT analyzer, Impact hammer testing, DEWE-soft 43.
