“…For water it amounts to 1 10200 1/K, while n-decane has 1 2230 1/K (Rahman et al (2013)). Hence, for the same ∆T , the phase shift in water is only approximately 1 5 of that in n-decane.…”

Measurement of diffusion coefficients is essential for simulation and prediction of oil reservoirs. Recently, a new experimental set-up has been built at Ryerson University to measure the transport coefficient of transparent liquid mixtures. Laser-based optical digital interferometry techniques using a Mach-Zehnder Interferometer have been used for measuring the diffusion coefficients. This method is non-intrusive, highly accurate, and can provide a detailed 2-D visualization of temperature and concentration fields. Five binary liquid mixtures of Decane (C10H22) - Isobutylbenzene (IBB), Decane (C10H22) - 1,2,3,4 Tetrahydronaphthalene (THN), Dodecane (C12H26) - Isobutylbenzene (IBB), Dodecane (C12H26) - 1,2,3,4 Tetrahydronaphthalene (THN) and Isobutylbenzene (IBB) - 1,2,3,4 Tetrahydronaphtha-lene (THN) have been selected. The mixtures have been prepared from pure C10H22, C12H26, IBB and THN for 50% mass fractions. These five binary mixtures are representatives of binary interactions between alkane, one-ring aromatic and two-ring aromatic hydrocarbons. The thermal designs of the diffusion cell, as well as the data analyze method, have been improved. A comparison of experimental data with theoretical analysis based on the Firoozabadi model for measuring thermodiffusion coefficient and Peng-Robinson equation of state (PR-EOS) for measuring the physical properties have been conducted. Experimental results showed a maximum deviation of less than 2% for IBB- C12H26 and THN-IBB and 9% for THN-C12H26 from the available benchmark results. Accurate knowledge of refractive index is highly relevant to correlations with concentration, temperature, wavelength and pressure in non-intrusive experiments carried out with transparent fluids. It can be used for the identification and characterization of pure materials and for the measurement of concentration of multi-component mixtures. In this current scope, refractive indices of five binary mixtures C10H22-IBB, C10H22-THN, C12H26-IBB, C12H26-THN and IBB-THN have been measured using both the Mach-Zehnder Interferometer and a multi-wavelength Abbemat refractometer. Temperature and concentration coefficients of refractive indices, or so-called contrast factors, as well as their individual correlation to calculate refractive indices have been presented for a wide range of visible spectrums such as 436 nm to 657 nm. Comparison with available literature and mixing rules shows that new correlations can predict the experimental data with deviations of less than 0.001.

“…Quantitative measurements of the optical properties of liquid mixtures can be obtained using the coherent light source interference phenomenon. This method is widely used in optical digital interferometry (ODI) [12][13][14][15][16], refractometry [15,17,18], optical beam deflection (OBD) [19][20][21], and other techniques [22][23][24][25].…”

“…because they are simplified multicomponent substances of hydrocarbon in natural crude oil reservoirs [30] and of great interest in the Differential Scanning Calorimetry (DSC) and Influence of Vibrations on diffusion in Liquid (IVIDIL) experiments currently taking place (on ground and in space) at the International Space Station (ISS) [31]. Although the properties of pure substances and their binary mixtures can be found in the literature [5,15], there is very little information available regarding ternary mixtures. In the present study, we measured the refractive index of different binary and ternary compositions (…”

Optical interferometry is a non-contact method used for the imaging and measurement of the optical properties of small or large objects with nanoscale accuracy. Interferometers are essential optical systems in engineering and medical science and are generally used to measure refractive index changes, cell pathology and shape irregularities. The ability to provide quantitative, non-invasive measurements makes interferometers suitable candidates for the study of living cells in vivo and in vitro applications. In this study, a simple interferometric system capable of providing precise measurements of the refractive indices of transparent and semi-transparent mediums was designed and developed based on the Mach-Zehnder arrangement. During the development phase, the system was used to take precise measurements of the contrast factors of the three hydrocarbon components 1,2,3,4-Tetrtahydronaphtalenene (THN), Isobutylbenzen (IBB), and Dodecane (nC12), prepared in the laboratory. The results were also compared with the corresponding results obtained using the Abbemat refractometer. The results were in agreement with those obtained from both techniques as well as the results obtained from the literature, confirming the accuracy of the measurements obtained with the new system with deviations of ± 2.50×10-3. Blood analysis is a routine procedure used in medical diagnostics to confirm a patient’s condition. Measuring the optical properties of blood is difficult due to the non-homogenous nature of the blood itself. In addition, there is a lot of variation in the refractive indices reported in the literature. These are the reasons that motivated this research to develop an empirical model that can be used to predict the refractive index of human blood as a function of concentration, temperature and wavelength. The experimental measurements were conducted on mimicking phantom, that shows better stability compared to human blood, using the Abbemat Refractometer. The values obtained using the model was in substantial agreement with those obtained experimentally with standard deviations of ± 2.33×10-3. Once the accuracy of the interferometric system was confirmed, the system was used to study the refractive index and morphology of human red blood cells. The results of the analysis confirmed the system’s ability to determine refractive index and/or blood hematocrit values with appropriate clinical accuracy.
