Nitrogen liquid properties

In either of the preceding cases, very high or very low C values, any attempt to calculate the effective adsorbate cross-sectional areas from the bulk liquid properties will be subject to considerable error. Nitrogen, as an adsorbate, exhibits the unusual property that on almost all surfaces its C value is sufficiently small to prevent localized adsorption and yet adequately large to prevent the adsorbed layer from behaving as a two-dimensional gas.

We now outline the main features of our potential models. The solvent molecules interact with an effective pair potential fitted to liquid properties. It consists of a Lennard-Jones (12-6) potential between each nitrogen atom plus electrostatic interactions between four charge sites on each molecule. These charges, and a neutralizing charge on the molecular symmetry axis, are chosen to yield the observed dipole moment. The Li -NH3 potential consisted of a coulombic term plus a Li-N (12-6) potential whose parameters were fitted to quantum calculations on the Li NH3 complex. ...

Loop Tests Loop test installations vary widely in size and complexity, but they may be divided into two major categories (c) thermal-convection loops and (b) forced-convection loops. In both types, the liquid medium flows through a continuous loop or harp mounted vertically, one leg being heated whilst the other is cooled to maintain a constant temperature across the system. In the former type, flow is induced by thermal convection, and the flow rate is dependent on the relative heights of the heated and cooled sections, on the temperature gradient and on the physical properties of the liquid. The principle of the thermal convective loop is illustrated in Fig. 19.26. This method was used by De Van and Sessions to study mass transfer of niobium-based alloys in flowing lithium, and by De Van and Jansen to determine the transport rates of nitrogen and carbon between vanadium alloys and stainless steels in liquid sodium.
