Opis:: The paper reports results of an analysis concerning the infuence of a computational domain discretization method on the numerical stability of a model as well as the calculation error. The topology of a packed bed of a granular material consisting of granules contacting tangentially in one point makes the modeling of heat and mass transfer due to the fluid flow in such a domain a chalenging task. Therefore, the contribution of this paper constitutes a summary of discretization methods with discussion and guidelines allowing one to effectively select the most favourable method dedicated to discretization of the domain. The validation using Particle Image Velocimetry and evaluation of the impact of inflow velocity on the experimental and numerical research results are also presented in the paper.

Opis:: The most popular devices for attenuation of mechanical vibrations are dampers or shock absorbers. Two main energy dissipation strategies can be generally distinguished: passive and active (semi-active). Passive vibration isolation methods are the most commonly used, mainly because of their simplicity and low maintenance costs. Among passive vibration attenuation techniques, also Particle Impact Dampers (PID) are involved. Classical PID solutions have some certain limitations. This paper aims at presenting the new concept of an adaptive tuned PID damper that can pretend to be placed among semi-active energy dissipation methods.
