- Abstract
Diffusion in a mixture with n components is described by n(n-1)/2 interdifusion coefficients at best. It is hopeless that any prgress could be reached in including actual diffusion data on trully multicompoent studies (as sea water, crude oils reservoirs, multicomponent chemical engineering, ...) unless: 1°) some simplifying evaluations of the diffusion coefficients can be performed, 2°) the evaluations follow some simplified rules. It is the scope of the DSC experiment (Diffusion and Soret Coefficients) that studies on the overall composition range a ternary hydrocarbon mixture of non similar componenst to start such a process. Presumed laws are to be verified and the" binary data obtained in gorund conditions complememtned by the fine measurments obtained in microgravity conditions on ternary solutions. The experiment is described and the expected outcomes detailed
