This formulation allows to consider particles of arbitrary shape and size and it can be applied to any laminar or turbulent flow. In the case of equal sized spherical dispersed elements, the most common case found in theliterature, the final expression for the interaction terms (contributions that describe the effect of the second phase on the continuous one) are obtained without great difficulties due to the high isotropy of the spherical shape. This task, in the general case of non–spherical non–equal particles is no longerstraightforward and the derivation of the appropriate general interaction terms is presented in §4. In the case that the dispersed elements are small enough, some simplifications can be further introduced leading to a final presentation that remembers that obtained for the simplest case of spherical particles, but where some of the quantities must be adequately redefined. 2008 artículo científico 1794-9165 https://www.redalyc.org/articulo.oa?id=83540703 en http://www.redalyc.org/revista.oa?id=835 Ingeniería y Ciencia application/pdf Universidad EAFIT Ingeniería y Ciencia (Colombia) Num.7 Vol.4
