Critical in chemical engineering processesPharmaceuticalsNuclear Fuel Cycle ProcessingCommercial Chemical ProductionWater Treatment

Fluid Mixing: A Critical Chemical Process

Fluid Mixing: A Worldly Chemical ProcessInherently present in many world processesFood ProductionOcean Current BehaviorsWeather Patterns

Hurricane Gonzalo. Photo credit: Alexander Gerst, ISS.Investigate Mixing Flow Behavior in Three Conducted Experiments:Observe flow patternsDetermine power consumption and power absorptionAnalyze mixing effectiveness

Fluid Mixing: A Better Understanding of the Phenomena

Fluid Mixing Equipment Set-up

Varied impeller dimensions and typePresence of bafflesIncreasing speed (25 rpm increments)Presence of Metal and Plastic PelletsFlow Pattern Experiment: Conditions

Dynamometer: measure force resistance of mixingDynamometer Head adjusted to prevent errorIncrements of 25 RPM

Power Consumption and Power Absorption Materials and Methods

Update picture when the one in the report is fixedNaClAdded in 25g increments at 125, 250, 375 and 500 RPMConductivity Meter (-1)Inserted into tank at 45 angleRecorded time elapsed upon reading stabilization

Electrolyte Mixing Effectiveness Materials and Methods

Update picture when fixedImpeller Type UsedFlat Paddle (4.3 x 6.2)Turbine ImpellerScrew Propeller

Electrolyte Mixing Effectiveness Impeller Type

Reynolds Number Laminar vs turbulent flow EddiesDrag force, func of areaBaffle ImpactsImpeller Dimensions and TypeFluid Mixing: Theory

Re = Reynolds number equation and its relation to speed with laminar/turbulent flow

Laminar and Turbulent Flow Effects on Fluid Mixing
