The car model is based on a hatchback passenger car that is known to have relatively high fluctuations in its aerodynamic loads. This study primarily focuses on the lateral motion of the flow on the horizontal plane to determine the effect of the flow motion on the straight-line stability and the initial steering response of the actual car on a track. This paper first compares the flow fields in the wake behind the above mentioned model obtained using conventional and high-speed planar PIV, with sampling frequencies of 8 Hz and 1 kHz, respectively. Large asymmetrically coherent flow structures, which fluctuate at frequencies below 2 Hz, are observed in the results of highspeed PIV measurements, whereas conventional PIV is unable to capture these features of the flow owing to aliasing. This flow pattern with a laterally swaying motion is represented by opposite signs of cross-correlation coefficients of streamwise velocity fluctuations for the two sides of the car model. Effects of two aerodynamic devices that are known to reduce the fluctuation levels of the aerodynamic loads are then extensively investigated. The correlation analyses reveal that these devices indeed reduce the fluctuation levels of the flow and the correlation values around the rear combination-lamp, but it is found that the effects of these devices are different around the c-pillar.}, language = {en} } @inproceedings{OttenGerhardsSchleseretal.2019, author = {Otten, Christian and Gerhards, Benjamin and Schleser, Markus and Schwarz, A. and Gebhardt, Andreas}, title = {Innovative Laserschweißtechnologie f{\"u}r additiv gefertigte Bauteile}, series = {Große Schweißtechnische Tagung}, booktitle = {Große Schweißtechnische Tagung}, publisher = {DVS-Media}, address = {D{\"u}sseldorf}, isbn = {978-3-96144-066-5}, pages = {150 -- 157}, year = {2019}, language = {de} } @inproceedings{PakPiegelerFeldmannetal.2006, author = {Pak, Daniel and Piegeler, D. and Feldmann, Markus and Schleser, Markus and Dilthey, Ulrich}, title = {Hybrid joints of textile reinforced concrete parts - designed for assembly}, series = {Textile reinforced concrete : proceedings of the 1.
