Abstract: A jet-mixed vessel can create a flow pattern similar to that in an agitated vessel with paddle impeller. Tangential flow and circulation flow can be provided by using a jet nozzle fixed at the center of a cylindrical vessel, where circulation flow can be controlled by varying angle of jet nozzle and jet flow rate. Numerical studies were performed using k-e turbulence models using computational fluid dynamic software FLUENT 6.1 to examine the effects of shape of tank on flow pattern and mixing characteristics in a jet mixer. Results show that better mixing is obtained for cylindrical bottom than the flat bottom for the same total mass flow rate.
