Experimental study of surface tension of ethane-methane solution in temperature range 213–283 K

AbstractIn this paper, the results of the experimental study on density, surface tension and optical properties of ethylene glycol-based nanofluids containing silicon dioxide have been presented. The nanofluid-air surface tension values were determined in the temperature range from 283.15 K to 318.15 K with Du Noüy ring method with the commercial equipment and self-made station. To determine the surface tension of a fluid, the information about its density is required; therefore, density of all examined nanofluids was measured in the same temperature range, and results were summarized in the paper. The refractive index of SiO$$_2$$ 2 -EG nanofluids was determined in the same temperature range in which the surface tension was examined. Finally, the extinction (UV–Vis spectra) of these materials was examined and presented.

Constant Friction

Ring compression tests were conducted at constant true strain rates in the temperature range of 900–975°C. The constant friction shear factor, m, was determined using a calibration chart. Scaling was permitted during the experiments in which a glass based lubricant was also used. Frictional conditions were affected most by the rate of strain; increasing it led to lower values of m.

Vertical Tubes

An experimental study has been made of the motion of long bubbles in closed tubes. The influence of viscosity and surface tension on the bubble velocity is clarified. A correlation of bubble velocities in vertical tubes is suggested and is shown to be useful for the whole range of parameters investigated. In addition, the effect of tube inclination angle on bubble velocity is presented, and certain features of the flow are described qualitatively.
