CFD modeling of waste cooking oil transesterification in a stirred tank reactor

In this paper, the numerical modeling of alkali-catalyzed waste cooking oil (WCO) transesterification in a 2-L stirred tank reactor (STR) is presented. Based on the Reynolds Average Navier-Stokes (RANS)equation, a 3-D model was developed to simulate the transesterification of WCO in a stirred tank r...
