“…Because the short-time Fourier transform uses 2048 points, the frequency resolution in all cases is approximately 1 mHz. Note that, since the signals associated with high ΔT values (particularly, ΔT = 40 K) and rapid melting are shorter, the spectral analysis of these cases is more difficult [63][64][65][66]. Fig.…”

“…Tables 2-6, indicate the runs in which spikes were detected. The Power Spectral Density (PSD) and warning maps based on the RMS values evaluated over one-third octave frequency bands [24,25] were used. As the signals were filtered to 6 Hz, this characterization focuses on the low frequency range which it is known to be the most harmful for the thermodiffussion experiments.…”

Thermodiffusion, which leads to a component separation in a mixture due to the thermal gradient, still does not have an unambiguous microscopic picture. Therefore, experimental studies, especially in convection free environment, are important. As part of the 4th campaign on the DCMIX project, thermodiffusion experiments on three compositions of the toluene-methanol-cyclohexane ternary mixture, on a mixture of fullerene-tetrahydronaphthalene-toluene and on a mixture of polystyrene-toluene-cyclohexane have been performed in microgravity conditions on board the International Space Station. A binary mixture of polystyrene-toluene has been filled into the companion cell for the campaign. The Selectable Optical Diagnostics Instrument (SODI), wich is a two-wavelength Mach-Zehnder interferometer for the ternary mixtures, plus a monochromatic Mach-Zehnder interferometer for the binary mixture, has been used in order to obtain the temperature and the concentration fields in the cells. Precisely, it is a 5-steps phase-shifting interferometry technique which is implemented with SODI, producing by means of laser illumination a set of 5 phase-shifted images of between them as function of the time. A total of 58 runs of various durations and at different mean temperatures have been conducted. Here, we evaluate the contrast of the interferograms, the quality in the phase stepping, the stability of the thermal regulation of the experiments and the level of environmental disturbances on board the space station during the campaign.
