Abstract: An algorithmic procedure has been designed/developed for computer aided Dimensional Analysis (DA) of chemical engineering processes. The main purpose of this software is to construct/select the best combination of dimensionless groups describing adequately a process under certain criteria. The creation/operation of an Ontological Knowledge Base (OKB) plays a central role in this procedure as it provides, inter alia, the means for filtering/reducing the dimensionless groups obtained by solving the system of dimensional equations according to the Buckingham Π Theorem. The successful implementation of this software is thoroughly presented step by step in a case of mass transfer (liquid drops moving in immiscible liquids).

Keywords: Dimensional analysis, knowledge management, ontology, metric space, buckingham Π theorem, dimensionless groups, XML
