Experimental validation of computational fluid dynamic codes (CFD) for liquid-solid risers in clean alkylation processes

Abstract

This manuscript, based on the presentation given by one of the authors (M.P. Dudukovic) at the Technological and Engineering Forum in Pančevo, May 21 2002, summarizes the use of the computer automated radioactive particle tracking (CARPT) and gamma computed tomography (CT) in obtaining the data needed to validate the Euler-Euler based CFD simulations for solids distribution, flow pattern and mixing in a liquid-solid riser. The riser is one of the reactors considered for acid solid catalyst promoted alkylation. It is shown that CFD calculations, validated by CARPT-CT data, show promise for scale-up and design of this novel reactor type.
