Onsager transport theory

WebIn this paper, we use the Stefan-Maxwell-Onsager formulation to calculate transport properties.24 ,25 40 41 This theory is formally equivalent to other formulations of concentrated-solution theory and attributes transport coefficients to frictional interactions between species.24 ,25 40 41 The frictional interactions are calculable with WebIn this region, the transport and rate equations are expressed in linear forms, and the Onsager reciprocal relations are valid. Therefore, sometimes this region is called the linear or Onsager region and the formulations are based on linear nonequilibrium thermodynamics theory.
