Our Project

Chemical Wave in Soret Effect (CWIS)

The purpose of this experiment, entitled Chemical Waves in Soret Effect (CWIS), is to visualize the chemical wave induced by the thermodiffusion of a binary liquid mixture. The chemical wave is a concentration front that rapidly propagates from the thermal boundaries of the liquid mixture, and which marks the beginning of the chemical sorting phenomenon called thermodiffusion, induced by an imposed thermal gradient. In order to eliminate the contribution of buoyancy and bulk convective fluid motion, this experiment takes advantage of the several minutes of milligravity provided by an Improved Orion sounding rocket, as a part of the REXUS 16 launch campaign. The launch vehicle...
