Data on participation in competitive R&D projects

MIP-072/2013 Akustinio poveikio aerozolio dalelių sistemoje modeliavimas diskrečiųjų elementų metodu,
MIP-072/2013 Discrete Element Simulation of Aerosol Particles under Action of Acoustic Field

Contract funding received by institution per year: 82000€

The project "Discrete Element Simulation of Aerosol Particles under Action of Acoustic Field” is aimed for the development of advanced modelling techniques and their applications. The project addresses development of a modern numerical research tool by extending capabilities of the discrete element method, and to apply it to investigate the behaviour of the system of aerosol particles under action of the acoustic field.
To achieve the manifested objectives, the physical model was formulated. Physical model treats aerosol as a system of the spherically shaped micrometric particles moving in three-dimensional viscous incompressible medium. The effect of the orthokinetic collisions and acoustic wake described by the drag forces, and mutual radiation pressure forces are taken into consideration. The already well approved conventional DEM methodology was applied to simulate aerosols. Thereby, a macroscopic motion of the particulate substance is described by forming and solving the equations of translational motion of individual particles. Traditional computing algorithm is extended by implementing the calculation of acoustically induced long-range inter-particle forces. The DEM algorithm was implemented into software package DEM-ACOUSTICS. The main part of the program, the solver, is written in Fortran programming language. The program shell aimed to control the entire computing sequence, and the pre- and post-processors used to generate input and output data are written using the Python programming. The parallel version of the solver modified to a multi-core processors is also developed.
Series of numerical tests were designed to search rationality of numerical model parameters or of individual calculation procedures. They include an evaluation of the sizes of the representative and of the effective agglomeration volumes, the time integration step, the rationality of the contact search or parallelization. The first numerical results when compared them with known analytical solutions and the results of the other researchers approved the known facts and phenomena. The latter can be attributed to the interaction of two equal particles, the radiation pressure effects, and the influence of acoustic frequency. The coupling of between acoustic interaction of poly-dispersed particles and gravitational effects, transformation of binary interactions into a collective behaviour along with decay of the inter-particle distance may be classified to the new results.
Experimental investigations cover the preparatory work, design and creation of the experimental stand, conducting of experiments and processing of their results. Composition consisting of solid particles having diameter of 5-10 mm reflects properties of the typical air pollutant. Acoustic field characterized by frequency 8.08 kHz and sound pressure level 138 dB was generated by the aero-acoustic sound generator, and field characterized by frequency 23.98 kHz and sound pressure level 135 dB was generated by the piezo-electric sound generator. Experiments were aimed to measure the concentrations changes of particulate matter.
The results confirmed the acoustic agglomeration effects of micro-metric size particles. The results revealed some problems to be solved. It became obvious, however, that performed studies determine only a part of problems caused by the acoustic impact. The developed model captures attractive motion in the dilute phase, but does not reflect the collective particle interactions, stick or rebound of particles at the final stage. This further research is required by using sophisticated mathematical models and modern experimental equipment.

The investigation of precision-length systems for dynamic processes
Precizinių ilgio sistemų dinaminių procesų tyrimai
Contract funding received by institution per year: 12000€

The optical linear encoders are the preferred choice sensors for positioning machine tools’ moveable parts. Machine tools’ errors have been traditionally focused on the analysis and performance of the machine tool structure until recent works have treated the encoder itself as a source of error. Encoder error quantiﬁcation has been done for several mounting conditions in static situations, but there is a lack of information regarding the performance of the encoder under dynamic solicitations. The aim of this work is to analyze the loss of accuracy of the sensor because of vibration for different mounting conditions. A ﬁnite element model of encoder has been developed and experimental results have been analysed using this model.
Photoelectric modular linear encoder L50 is an incremental encoder and has the measuring length from 3.240 up to
30.040 mm, grating period of 40 µm and accuracy of any meter within the ML of up to ±10 µm.
In this work analytical dynamic studies of L50 linear encoder were performed. Investigations consisted of calculations of the linear encoder construction main parts (encoder head, encoder frame and encoder steel tape): modal analysis of the L50 encoder head; Investigations of the response of the L50 encoder head to the harmonic excitation; Modal analysis of the L50 encoder frame with steel tape.

Data for assessind developement of R&D activities and description of the available R&D infrastructure

The R&D infrastructure of the Unit being assessed consists of the Faculties of Mechanics and Transport Engineering, the Aviation Institute and the Faculty of the Environment. Each Faculty is involved in different areas that are interrelated both in terms of their research, and the R&D activities. The consolidation of international projects has been undertaken with a view to strengthening the R&D performance in different areas. The process involves pooling the skills of the different researchers active in the division being assessed, thus considerably enhancing the performance in the R&D area.
Following the reorganization of 2017, the infrastructure of the Faculty of Mechanics was mostly centered in three major Departments and research laboratory engaged in R&Dwork related to research of mechanical processes, solid particle analysis and practical studies, materials science, or the automation of production lines while referring to the ideas of the Industry 4.0. Furthermore, the R&D activities at the Faculty of Mechanics are related to the Integrated Components for Complexity Control in affordable electrified cars (3C car project); the project is being implemented in cooperation with the Faculty of Transport Engineering researchers.
