CFD simulation of biodiesel production using mixed flow impeller in baffled and unbaffled stirred vessel

In this paper, the numerical modeling of alkali-catalyzed waste cooking oil (WCO) transesterification in a 2-L stirred tank reactor (STR) is discussed. Based on the Navier-Stokes equation, the liquid flow in the STR was resolved using unstructured, non-uniform mesh with the sst- κ-ω, κ-ε and RSM t...
