The quantity ‘independent restriction’ solely depends on the structure of the molecules. For example, in the case of a monoatomic gas, B=0, as it can move freely. A diatomic gas is not allowed to move along the bond. Degree of freedom for different gases: Atomicity of gas Degrees ...

The first-order effects include the isothermal and thermal gas slips characterized by the coefficients Cm and KTS, respectively. p]In contrast to a monatomic gas, the molecules of diatomic and polyatomic gases have internal degrees of freedom, which considerably complicates the kinetic equation [9]...

translational degrees of freedomgas-surface interfacesdiatomic gasThe exchange of energy and momentum during the collision between molecules of a diatomic gas with translational and rotational degrees of freedom and solid surfaces is studied by classical trajectory calculations. The gas molecules are ...
Using the half-space moment method, the problem of the slip of a diatomic gas along a rigid spherical surface is solved within the framework of a model kinetic equation previously proposed which takes into account the rotational degrees of freedom of the gas. Second-order slip coefficients (...

Using molecular-dynamics computer simulations, we investigate the dynamics of the rotational degrees of freedom in a supercooled system composed of rigid, diatomic molecules. The interaction between the molecules is given by the sum of interaction-site potentials of the Lennard-Jones type. In ...
