Project manager: Dr Eng. Vladyslav Yuriiovych Shybetskyi

Project acronym: RESPIRATION

Consortium budget: PLN1 005 967,00

Project type: NRC’s research project (POLONEZ BIS-2)

Project location: Łukasiewicz Research Network – Industrial Institute for Automation and Measurements (PIAP)

Awareness-building description of the project:

The aim of the project is to solve the problem of clearing air from fine particles, smaller than 2.5 μm in diameter, by increasing efficiency of acoustic field pre-cleaning technology using resonators.

The pioneering nature of the project is determined by:

  • the use of resonators installed in the path of the gas being cleaned of fine particles.
  • use of finite element computer modelling to take into account all factors affecting the acoustic coagulation process.

The research objectives are:

  1. to develop a theoretical mathematical model of a process consisting of three interrelated parts: a model of the oscillation process of resonators represented as rods of complex geometry under the action of high-frequency oscillation; a model of the process of propagation of high-frequency oscillations in a continuous medium (air) through resonators; a model of the movement of fine particles in air under the influence of high-frequency vibrations and their interaction with resonators;
  2. to develop a complex computer model of the process of propagation of high-frequency oscillations in an acoustic environment (air) through resonators of different designs in the ANSYS analysis system, consisting of three interrelated parts: development of a computer model of the process of propagation of high-frequency oscillations in the acoustic environment (air) through resonators of different designs; development of a computer model of the hydrodynamics of air movement with dispersed particles through resonators of different designs; development of a natural vibration model of the acoustic coagulation system and the occurrence of resonance in it;
  3. to investigate the effect of high-frequency oscillations by resonators of optimised design on the quality of air purification by means of a physical experiment. Determining the correctness of the influence of the granulometric composition of fine particles, their concentration, mass and nature on the treatment process;
  4. verification of data obtained from modelling and physical experiment;
  5. optimisation of the resonator design to increase coagulation efficiency;
  6. to carry out technology scaling and experimental studies of the feasibility of using mobile devices of air purification systems based on acoustic coagulation combined with robot autonomy to eliminate smoke and high concentration of fine particles in a confined space for rescue operations;
  7. to disseminate the project’s results by publishing them in high-impact publications and describing the results at international conferences; create a website; conduct seminars; and publishing the results in “Cordis” and “Horizon” journals.

Mathematical modelling methods based on the equations of orthokinetic theory, hydrodynamics of fluid motion (Navier-Stokes equation) and acoustic excitation theory will be used to develop a theoretical mathematical model. Computer simulations will be carried out using the finite element method of the ANSYS analytical system. It is planned to use the principles of three-dimensional modelling using CAD software to build geometric research models.

The study of resonance phenomena is planned to be carried out in two stages:

  • determination of natural frequencies by vibration-modal analysis (ANSYS)
  • determination of resonance manifestations in the solidification system by the Acoustic Response method – Acoustic Response (ANSYS)

The effect of resonators on gas flow hydrodynamics will be determined using Fluent computational hydrodynamics (ANSYS): the movement of the gas is described by the Realisable K-e turbulence model; fine particle trajectories are provided by the Discrete Phase model. The project provides for a quantitative analysis of the research results. The result of the computer simulation will be plots of variables, contours, vectors, trajectories of particle movement and values of particle number, pressures, velocities. The experimental study determined the number of particles after air treatment, the pressure loss in the system, and the energy consumption to generate oscillations. All these parameters will be a primary information. They will be recorded by

It is planned to use regression analysis to process the experimental data and establish relationships between their values.
