Kinetic Theory of Nonspherical Molecules. IV. Angular Momentum Transport Coefficient

The kinetic theory of nonspherical molecules, as developed earlier, leads to an expression for the flux of angular momentum, involving several new transport coefficients. This paper is concerned with the evaluation of the first of these coefficients, L(0). The expression for this quantity as given earlier, is simplified by carrying out certain integrations explicitly. The resulting expression depends directly only upon the geometry of the molecular model. As an example, we consider the spherocylinder. The final integrations are then carried out analytically. The resulting expression for the dimensionless transport coefficient depends only upon three dimensionless groups of parameters characterizing the shape and mass distribution. The numerical results are illustrated graphically.
