TY - JOUR TI - EASY WAY TO CALCULATE THE ANZELIUS — SCHUMANN J FUNCTION AU - Bačlić Branislav AU - Gvozdenac Dušan D AU - Dragutinović Gordan JN - Thermal Science PY - 1997 VL - 1 IS - 1 SP - 109 EP - 116 PT - Article AB - The paper deals with the computational aspects of the so called Anzelius function. This special function is the fundamental one for describing the kinetics of a fixed-bed adsorber and is widely used on the theory of : breakthrough curves not only in adsorption and ion exchange, but in the other operations with isomorphous mathematical models as well. Instead of the use of graphical and tabular presentations of the numerical values of this function (what is common practice in chemical engineering literature) the paper proposes a simple algorithm as an alternative for its evaluation. The algorithm is very efficient and extremely accurate for entire range of parameters of interest.
