Biodiesel is renewable burning fuel that is made from waste vegetable oils, animal
fats, or recycled restaurant grease that beneficial in diesel vehicles. The right type of
mixing blade used in biodiesel reactor can reduce the maintenance cost and improve
the biodiesel production. In this study, the pressure distribution and pressure location
of three bladed mixing propeller and Rushton blade were determined by running the
simulation using ANSYS software. The simulation was carried out by transferring the
CAD model of both blades to the ANSYS FLUENT workbench. After that, grid
independent test were carried out and turbulence model from viscous model panel
were selected. The two types of different biodiesel mixing blades have shown different
pattern in term of pressure distributions. The Rushton blade type has higher pressure
distribution along the mixing fluid and has highest pressure at its tips compared to
three blade mixing propeller and it proves that Rushton Blade is more effective for
biodiesel reactor.
