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);

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

The purpose of this mini-symposium is to constitute a forum for the exchange of knowledge concerning latest research developments in the field of Structural Vibrations. Within this context, innovative methods for the design and analysis of structures subjected to various types of dynamic loading, due to earthquake, wind, wave or other kind of excitation, will be discussed. Linear or non-linear, elastic or inelastic structural models that accompany the aforementioned vibration absorption techniques will, also, be considered. It is anticipated that the Symposium will promote the dissemination of research results and ideas on Linear or Nonlinear Structural Vibration procedures and their applicability to structures.

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.

Rotor dynamics have a crucial role in the industrial machinery and turbomachinery (e.g. power generation, aircraft engines, marine propulsion), health care (e.g. dentist drill, tomography) and our daily life (e.g. automobiles, ventilators). The dynamics of a rotor is affected by its structural design, its support, its attachments (blades, copper wires) and its environment.

The Submerged Floating Tunnel (SFT) is an innovative and great potential traffic structure for crossing long waterways and deep straits. Because SFT is in the underwater environment of the ocean and long waterway, the behavior of SFT is very complicated under the action of current and wave, as well as the running vehicle load within SFT and accidental loading, such as impact, explosion and seismic force. The aim of Mini-symposia (MS) on SFT is to discuss some of key Issues related to SFT and to share the recent advances, so the MS will focus on:
