Novel experimental ignition delay time (IDT) data of three binary TRFs of varying n-heptane/toluene ratios have been obtained in a high-pressure shock tube and in a rapid compression machine at conditions relevant to novel engine operation. Measurements have been performed at two pressures (10 and 30 bar), and at three fuel/air equivalence ratios (0.5, 1.0 and 2.0) for TRF mixtures of 50\%, 75\% and 90\% by volume toluene concentration, over the temperature range of 650-1450 K. It was found that, increasing the n-heptane content, led to an increase in reactivity and shorter measured IDTs. Reduced sensitivity to the equivalence ratio was observed at high temperatures, especially for high toluene content mixtures.

A TiAl specimen is encapsulated with multilayer stainless steel foil and glass. The steel foil layers prevent the heat loss through radiation and the glass layer reduces the temperature decrease through conduction. First, the effect of steel foil on the cooling rate was investigated. Cooling curves were recorded for TiAl specimens without steel foil layer, with 1, 2, 3 and 4 layers of steel foil, as well as with 3 coated steel foil layers, respectively. While the unprotected specimen cooled from 1200 °C to 1100 °C within 12 s, the specimen with 3 coated steel foil layers needed 52 s for the same temperature decrease. The efficiency of the glass layer was examined with forging of steel specimens. The cooling rate during forging of the specimen with a glass layer is only half of that without a glass layer. Based on the results, Ti-45Al-0.5Mo-0.5Cu-0.2Si specimens, canned with steel foil and glass, were successfully forged at strain rates of 0.1 s-1 and 0.04 s-1 with warm dies which were heated to 500 °C.

The influence of final states, photoionization cross-section, and adsorption of residual gas molecules in an ultrahigh vacuum environment are discussed in terms of their impact on the VBS. We find that VBSs recorded with monochromatized Al Kα radiation are most closely comparable to the ground state density of states (DOS) derived from quantum mechanics calculations. We use the Al Kα-excited PES measurements to correct the energy scale of the calculated ground-state DOS to approximate the "true" ground-state d-band structure. Finally, we use this data to test the d-band center model commonly used to predict the electronicproperty/ catalytic-activity relationship of metals. We find that a simple continuous dependence of activity on d-band center position is not supported by our results (both experimentally and computationally).}, language = {en} } @misc{ZhangGeyerSilvaetal., author = {Zhang, Tingyi and Geyer, Thomas and Silva, Charitha de and Fischer, Jeoffrey and Doolan, Con and Moreau, Danielle J.}, title = {Experimental Investigation of Tip Vortex Formation Noise Produced by Wall-Mounted Finite Airfoils}, series = {Journal of Aerospace Engineering}, volume = {34}, journal = {Journal of Aerospace Engineering}, number = {6}, issn = {1943-5525}, doi = {10.1061/(ASCE)AS.1943-5525.0001315}, language = {en} } @misc{ZhangMoreauGeyeretal., author = {Zhang, Tingyi and Moreau, Danielle J. and Geyer, Thomas and Fischer, Jeoffrey and Doolan, Con}, title = {Dataset on tip vortex formation noise produced by wall-mounted finite airfoils with sinusoidal and porous tip geometries}, series = {Data in Brief}, volume = {30}, journal = {Data in Brief}, issn = {2352-3409}, doi = {10.1016/j.dib.2020.105471}, pages = {10}, language = {en} } @misc{ZhangMoreauGeyeretal., author = {Zhang, Tingyi and Moreau, Danielle J. and Geyer, Thomas and Fischer, Jeoffrey and Doolan, Con}, title = {Dataset on tip vortex formation noise produced by wall-mounted finite airfoils with flat and rounded tip geometries}, series = {Data in Brief}, volume = {28}, journal = {Data in Brief}, issn = {2352-3409}, doi = {10.1016/j.dib.2019.105058}, pages = {8}, language = {en} } @misc{ZhangWangPyczaketal., author = {Zhang, Haoyin and Wang, C.

This rig features a 3 kW direct-drive electric motor with three rotor blades of 1.1 m diameter. In the experiments, a variety of different tip modifications was tested regarding their noise reducing performance, including different porous materials that were manufactured using rapid prototyping. Acoustic measurements were performed at different rotationals speeds and blade angles using a ring-shaped microphone array consisting of 60 evenly spaced microphones. The rotational speed was measured using a laser sensor. Different beamforming algorithms were used in post-processing to help analyzing the data. The results show that porous tips can lead to a notable noise reduction at low frequencies, but a small penalty at medium and high frequencies which may be due to the surface roughness of the porous tips. This trend seems more severe for lower blade angles than for higher ones. These findings agree well with those obtained from the previous wind tunnel measurements.}, language = {en} }
