An Agitation Experiment With Multiple Aspects

Authors

  • Jordan L. Spencer Columbia University

Abstract

This paper describes a multifaceted agitation and mixing experiment. The relatively inexpensive apparatus includes a variable-speed stirrer motor, two polycarbonate tanks, and an instrumented torque table. Students measure torque as a function of stirrer speed, and use conductive tracer data to estimate two parameters of a flow model. The effect of agitation intensity on heat transfer, on the motion of beads added to the fluid, and on the dissolution of salt crystals can also be studied.
