Abstract
This paper presented simulation analysis of stress distribution along a mixing blades propeller used in biodiesel reactor tank. The mixing blade types used are: (1) three bladed mixing propeller, (2) pitch turbine blade and (3) Rushton blade. ANSYS FLUENT software was used to run the simulation. The maximum stress occurs when using three bladed mixing propellers type. The minimum stress occurs when using the Rushton blade. Therefore, the Rushton blade is the best blade used for biodiesel reactor. Stress concentration is observed at the fillet for all blade types. The selection of the right type mixing blade can improve the biodiesel production and lower the maintenance cost. The result obtained from the simulation is agreed well with the published data.
