Fluids & Mechanics

The expertise developed in recent years in the fields of multiphase systems, structure dynamics and engine technology, have been pooled together in the research area “Fluids & Mechanics”. The unique strengths of MCI are the interdisciplinary approaches and varied comprehensive methods such as the experimental verification of simulations or the application of control engineering concepts in mechanical systems. Nonetheless, it is of prevailing importance to find the most appropriate solution for the respective challenge with regard to the general requirements.

 

Particle & Separation Technology

In the field of particle and separation technology, knowledge from fluid analysis is used, for example, to optimize particle separators or to design them for special requirements. This research area focuses on the separation of particles by means of centrifugal separators, especially with counter-flow and uniflow cyclones. The latter type of cyclones offers many advantages due to their compact design and is therefore used in various technical applications for gas-particle separation (e.g. intake air pre-cleaning of motor vehicles, FCC plants, exhaust gas cleaning systems, etc.). The investigation by means of state-of-the-art experimental and numerical methods such as laser-based flow measurement technologies, online particle characterization as well as precise manufacturing processes, including rapid prototyping, allow the investigation of a wide variety of applications in detail.

Equipment & Process Optimization of Dispersed Systems

Like many other industrial sectors, the material-converting industry is facing great challenges in the optimization of processes and apparatus. Experimental know-how in methodology and prototype construction enable detailed parameter optimization for the further development of an apparatus design. Research areas comprise particle separation, bulk solids technology or emission reduction of particulate matter for example. In addition to the technical evaluation (also in the context of a meaningful linkage of the unit operations in process engineering in the plant) economic considerations (e.g. cost-benefit analysis, LCA, ...) are also applied here.

Computational Engineering

Simulation technology forms a core area of education in several MCI study programs and has established itself as an independent and interdisciplinary research area. In addition, the modern research process has long since become indispensable for modelling, simulation and visualization with the aid of high-performance computers. From classical data engineering, i.e. the collection, processing and validation of data, to complex mechanical (FEM, MBS), fluid mechanic (CFD, LB), acoustic, electromagnetic and control engineering simulations, and on to digital twins, engineering problems can be investigated and described.

Structure Dynamics

Due to the variety of moving parts and components in mechanical engineering practice, structural dynamics is of particular importance. The related structural vibrations can lead to material fatigue or undesirable acoustic behavior. Both, experimental and numerical investigations in the field of structural dynamics are conducted by the research unit. Alongside vibration measurements in an in-house laboratory, also field measurements are carried out. The results of these measurements are used to validate the numerical models as well as to determine unknown model parameters. These validated numerical models are the basis for subsequent optimization procedures.

Engines & Emissions

Given the fact that internal combustion engines represent the backbone of current mobility solutions and play a significant role in the area of energy supply, the research division Engines & Emissions particularly addresses issues related to alternative fuels, internal combustion and technologies for the reduction of emissions.

IgnitionLab
Duration:
2017 - 2019

Description:
Gas engines are a reliable means of producing electricity and heat from combustible gases. Large-scale gas engines have now become leaner (λ> 1), especially as they enable low-emission operation with regard to both nitrogen oxide and carbon monoxide emissions. To increase the thermal efficiency of a fast combustion and high compression ratios are sought. The former can be increased for example by a targeted charge movement, i.e. the movement of the fuel-air mixture in the cylinder. This increase in turbulence and the increased pressures associated with the lean mixture, however, require increased ignition voltage and extended spark duration of the spark plug in these engines. In addition, a distraction of the spark is observed. The cause of this spark deflection is currently not completely clear, but could be due for example to external flow or electrochemical effects. Shortened life of these ignition devices is evident from the above-mentioned points of view, and thus research and ultimately adaptation or optimization are urgently needed.

Development of semiceramic catalyst supports
Duration:
2017 - 2019

FH-Prof. PD DDipl.-Ing. Dr.techn. Lukas Möltner

Team:
Verena Schallhart, BSc, MSc

Description:
The aim of the planned research activities is the development of a new semi-ceramic material for an electrically heated catalyst support. Unlike heaters already on the market, the direct introduction of heat into the catalyst offers an advantage in response. The second advantage is the high heat capacity of the ceramic base material, which, as soon as the catalyst is at operating temperature, prevents too rapid cooling.

Analysis Engine Oil 2018
Duration:
2018 - 2019

Project Lead:
FH-Prof. PD DDipl.-Ing. Dr.techn. Lukas Möltner

Team:
Verena Schallhart, BSc, MSc

Description:
During the production of motorcycle engines, these are filled after completion with engine oil, which is discharged after a subsequent test run again. The reason for this procedure lies in the fact that at first start a considerable amount of metal abrasion and foreign matter from the production of engine oil are flushed out of the engine and this is therefore no longer suitable for further use. For economic as well as ecological aspects, the drained engine oil is collected and regenerated for reuse. In addition to the entry of solids, which can be separated by mechanical separation (filtration) efficiently, the production-related entry of water-containing coolant is another source that can lead to an impairment of the lubricant quality. As part of the research activities, a process engineering optimization of this oil treatment is carried out.

DI Dr. Andreas Mehrle

Jasper Volmer, MSc

Description:
When a machine is built, a large number of load cases and scenarios need to be examined through numerical analysis beforehand. However, these simulations are usually limited to individual components and are not able to portray their complex interactions. Consequently, unexpected and unwanted phenomena occur, especially if multiple physical domains are involved. A "digital twin", however, serves as a virtual counterpart of the entire machine. It allows a complete depiction of the machine and its simulation with different levels of detail, depending on its resources. In particular, the "digital twin" should be able to display multiphysical interactions, which appear in recent developments, such as multivariable control, autonomous driving and predictive maintenance. This project is supported by the Tyrolean Government.
