Research plays an important role for an innovative company like bionic surface technologies. Research projects in different areas of expertise provide insights in new specialist fields. That leads to a greater experience in the field of CFD simulations in general. In the end also our partners benefit from the new gained know how. To get an overview over the recent projects, each research project is briefly described and presented in the following.

In the beginning of 2015 the EU funded H2020 project “R2R Biofluidics” startet. The  Horizon 2020 program, is in fact the world largest, transnational program for research and innovation (see also H2020). With project partners from Austria, Germany, Denmark and Spain a process chain for the production of bioanalytic lab-on-chip devices is going to be developed during the four year project. Through roll-to-roll (R2R) imprinting two demonstrators are going to be developed which can be used in clinical diagnostics. Demonstrator 1 is a diagnostic chip with imprinted microfluidic channels based on chemiluminescence detection using photodetectors and containing imprinted optical nanostructures for light coupling and thus improving device performance. Demonstrator 2 contains cell-chips with imprinted cavities and micro- to nanoscale channels for controlled neuron culturing which are to be applied in high throughput drug screening. In this project bionic surface technologies is responsible for the challenging simulation of the micro and nano channels. So the ideal fluidic design of the channels can be guaranteed. The generated know-how is already being used in further developments in micro- and nanofluidics with different partners. More about the project can also be found under www.r2r-biofluidics.eu.

Another project which is also funded by the H2020 program is the project “Riblet4Wind”, which deals with the usage of riblets on large wind power plants (more about Riblets). Through the application of riblets on the rotor blades the drag to lift ratio is reduced and therefore an increase in efficiency of 6% can be reached. Together with Partners from Germany, Denmark, Spain and Great Britain different methods of application are going to be investigated and tested. bionic surface technologies contributes with the own developed riblet alorithm to the calculation of the riblets to guarantee the maximum benefit of the riblets.

The project “ReLam” is funded through the program TAKE OFF. TAKE OFF  is a program for the implementation of the FTI-strategies for the Austrian aviation sector (see also TAKE OFF). It should guarantee the competitiveness of the innovation location, accelerate the reduction of pollutants and the protection of the environment and improve the aviation system overall through innovation.

ReLam startet in 2014 and deals with the relaminarisation and the development of numerical codes. In the course of this research project two papers with the titles „Comparison of RANS and Embedded LES Calculations with Measurements of Transitional Flow Along a Flat Plate“ and „RANS and eLES Simulations of Relaminarization“ have already been published.

ReLam stands for “Untersuchung von Relaminarisierung in den Grenzschichten von Triebwerksstufen zur Wirkungsgradverbesserung”

German for: Examination of relaminarisation in the boundary layer of turbine levels for efficiency optimization

Another project in the aviation sector deals with turbines and different approaches to reduce noise levels at the turbine exit casing. Some of these modifications are altering surface roughness of the blades and the walls, thus affecting boundary layer development. Most important outcomes of the project “hallstaTt” are suggestions and recommendations how to reduce noise level of aero engines considering aeroelasticity in order to perform a holistic optimisaton.
bionic surface technologies contributes with different CFD simulations to the cooperation project with the TU Graz, which has started in July 2015.

Together with the University of Technology Graz and the company Springer und Pieringer EDV Dienstleistungen OG bionic surface technologies has startet the project “EisenerZ” in 2016. The goal of the research project is the experimental and numerical examination of the impact of inflow-inhomogeneity on the vibrational response of a turbine rotor. The challenge for the numeric is that the whole scale of 360° has to be modelled and simulated. These calculations take a lot of time and ressources, so parallel to the measurements and the numerical simulation a seperate calculation tool is being programmed to calculate the stability of the system in a short time.

EisenerZ stands for Einfluss von Zuström-Inhomogenitäten auf die Schwingungsanregung einer NDT moderner Zweikreistriebwerke

German for: Influences of the inflow-inhomogeneity on the vibrational response of a NDT modern turbofan engine

TURANDOT stands for TURbulence ANd Optical Measurements for Duct Surface Optimization in Turbofans.

In the research project “TURANDOT” everything is about turbines. To increase the efficiency of aircrafts, one important key component is the intermediate turbine duct between the High Pressure Turbine and the Low Pressure Turbine. Different factors lead to a bad flow quality in this area. One of the aims of this project is to gain new insight into the inermediate turbine flow physics and to characterize the evolution of turbolence through the duct. Furthermore the potential of drag-reducing surface modifications are examined. Through the FFG funding project “Beyond Europe” it is possible to examine the potential of drag reducting modifications of surfaces together with international partners from the US and India, as well as the TU Graz.

The research project “SIMSider” has the development of simulation algorithms for a complete roll-based coating and imprinting process for micro and nano structures as a goal. On the basis of simulated and experiemental verified results a ideal process should be developed, so that the nano structures can be produced functionally and at the same time in an industrial scale. Especially for bionic surface technologies this development of the procedure for micro and nano structures is of great interest for the own riblets. The project was submitted in FTI initiative “Produktion der Zukunft” (Production of the Future) together with Joanneum Research Materials and the german partner company fmp technology GmbH. SIMSlider has started in 2017 and will continue in the next three years.

SIMSlider stands for Simulation of Roll imprinting – Slot-Die-Coating, Nano-Imprinting and Demolding in R2R
