![]() When arriving at a site of a surface, an adatom has three options. 5 However, cores made from amorphous metal have a stacking factor of around 0.8, compared to 0.96 for silicon steel. Net cross sectional Area Stacking factor (also called Iron factor) (Ks) gross cross. ![]() Stacking factors are typically 0.95 or higher for transformer cores 4 and machine stators. EFF Efficiency that is the ratio of the useful power to the. For use in adsorption from liquids the equation is expressed based on solute density (molecules per volume) rather than the pressure. Laminated cores always have a stacking factor less than unity a stacking factor of unity implies no laminate at all. The original formulation was for molecules adsorbing from the gas phase and the equation was later extended to adsorption from the liquid phase by comparison with molecular dynamics simulations. ![]() The coefficient is a function of surface temperature, surface coverage (θ) and structural details as well as the kinetic energy of the impinging particles. Sometimes the symbol S c is used to denote this coefficient, and its value is between 1 (all impinging atoms stick) and 0 (no atoms stick). Sticking coefficient is the term used in surface physics to describe the ratio of the number of adsorbate atoms (or molecules) that adsorb, or "stick", to a surface to the total number of atoms that impinge upon that surface during the same period of time. ![]()
