Separation experiments were conducted on light water–heavy water mixtures using a mixed-fluid separation device that combines thermodiffusion induced by a temperature gradient with laminar flow. The device separates the mixture by dividing and collecting the fluid through upper and lower channels while preserving the concentration gradient generated by thermodiffusion. This presentation reports the experimental results of light water–heavy water separation and discusses the concentration dependence of the separation performance.
