Abstract

A new method is introduced to measure the thermal diffusion coefficient, based on moiré deflectometry. e soret coefficient of sucrose-water solution of 10 percent is measured. A cell containing the homogeneous solution of sucrose and water solution is placed in a moiré deflectometry system. Using a water cooling system, the two end of the cell is held on different temperatures T0 and T1. is causes a linear temperature gradient inside the solution and a mass transfer occurred from one side to other side. A concentration gradient is also occurred over time, whi causes mass transfer in opposite direction. Finally these two phenomena rea to equilibrium and the net mass transfer gets zero. By cuing off the temperature difference, first, the temperature gradient, and then the concentration gradient, disappears, and causes the displacement of moiré fringes. e moiré fringes deflections are used to measure the refractive index gradient inside the cell and then the soret coefficient is derived.
