“…Its density was f = 950 ± 10 kg ⋅ m −3 . (Details of these measurements are provided in Rousseau (2019)-Annex D.) These values were close to those obtained by Chen et al (2012). According to these authors, surface tension was about f = 31 ± 1 mN ⋅ m −1 , which is a factor of 2 lower than that of water.…”

This paper presents image velocimetry measurements on turbulent flows adjacent to a permeable bed made of randomly packed glass particles. For measuring flow velocities inside the bed, the refractive index of the glass particles was matched with that of the fluid. By continuously scanning in the transverse direction, we measured the streamwise and vertical velocity components within a three-dimensional domain (3D2C-PIV), including first-and second-order turbulent statistics. We established how the scanning travel speed is associated with the laser sheet thickness and the space-time velocity fluctuations for collecting reliable measurements. The methodology was applied to free-surface flows over a sloping bed under low relative submergence and supercritical conditions. Space-and time-averaged profiles were obtained in a representative elementary volume as defined by the double-averaging procedure (Nikora et al. in J Hydraulic Eng.127(2):123-133, 2001). A turbulent boundary layer over the rough bed was observed when experiments were run at intermediate Reynolds numbers Re = O(1000) . Apart from measuring subsurface velocities, this method shed light on the part played by the rough bed in the overall flow dynamics: the roughness layer was a buffer region within which porosity varied sharply and turbulent stress was rapidly dampened.

“…An Atago RX 5000 refractometer was therefore used to measure samples of the interstitial fluid. The initial mixture was based on the measurement tables of Chen, Lin & Tu (2012). Further adjustments to obtain the desired value of were done by adding small quantities of either ethanol or benzyl alcohol.…”

“…It was shown in Figure 2 that the excess molar volumes of benzyl alcohol with ethanol, 1-propanol, and 2-propanol are in agreement with the reported data. 5,6,15 The densities of pure liquids and their binary mixtures were measured by using single capillary pycnometer in ref 6. The reported data by Venkatramana et al 17 for benzyl alcohol with 1-propanol and 1-butanol are not good quantitative agreement with Nain et al 6 and this work data.…”

Experimental data of densities, viscosities, and refractive indices of {(benzyl alcohol + methanol), ethanol, 1-propanol, 2-propanol, 1-butanol, and 2-butanol} binary mixtures were measured at T = 298.15 K and ambient pressure (81 500 Pa) using an oscillating densimeter, Ubbelohde capillary viscometer, and digital Abbe refractometer, respectively. Values of excess molar volumes, V m E , of the binary mixtures in the liquid phase at T = 298.15 K have been derived from density measurements. The experimental data are used to calculate partial molar volumes, V i , excess partial molar volumes, V i E , excess partial molar volumes at infinite dilution, V i E,∞ , deviations in the viscosity, Δη, and deviations in the refractive index, Δn D , excess refractive index, n D E , and kinematic viscosity, ν. The calculated quantities V m E , Δη, Δn D , and n D E have been correlated with the Redlich−Kister equation. The excess partial molar volumes, V i E,∞ , and enthalpies, H i E,∞, at infinite dilution of the binary mixtures were computed by ab initio method at the M05-2X/6-311++G** level of theory using PCM theory in the liquid phase. The general agreement found between the computational and the experimental liquid-phase data gives confidence to calculate the excess partial molar volumes and enthalpies at infinite dilution.
