computer model

A computer model of a liquid is set up, in which between 100 and 1,000 molecules are contained within a cube. There are now two methods of proceeding: by Monte Carlo calculation or by what is called molecular dynamics; only the latter is discussed here. Each…

…interest in the use of computers to generate theoretical expressions for the activity coefficients of solutions. In many cases the calculations have been restricted to model systems, in particular to mixtures of hard-sphere (envisioned as billiard balls) molecules—i.e., idealized molecules that have finite size but no forces of attraction. These…

…used along with computer forecast models to predict the future path and intensity of the storm. There are three basic types of computer models. The simplest ones use statistical relations based on the typical paths of hurricanes in a region, along with the assumption that the current observed motion of…
