5 Experimental and Numerical Investigation of Flow Phenomena During the Solidification Process HBCU/MI ETC Project 1
6 BackgroundSolidification plays an important role in engineering, environment, and materials processingExamples: Solidification of castings and ingots, crystal growth, welding, polymer production, freezing in oceans, freezing of moist soils, and radioactive waste managementThis project supports DOE develop technologies that improve:Materials processing and manufacturingEnergy efficiencyProduct qualityRadioactive waste treatment
7 ObjectivesUnderstand physics of solid phase formation during the solidification of a binary mixtureFocus on study of effects of convection pattern on the solidification processCurrent project involves:Experimental investigation of fluid and thermal aspects of the solidification processNumerical study of transient phenomena, heat and mass transfer processes, and phase transition phenomenon.
8 Technical ApproachBinary solution: Ammonium chloride-water (NH4Cl-H20)Test chamber: TrapezoidalExperimental Study:Temperature measurements:32 thermocouples (22 thermocouples for the solution and 10 thermocouples for the two cooling plates)Velocity Measurements:Particle Image Velocimetry TechniqueThickness of frozen layer:Measured from the PIV imagesNumerical Study: Modeling of Solidification Process using Fluent 6.0.
10 TasksStudy the effect of cooling conditions on the solidification processStudy the effect of initial concentrations on the solidification processStudy the effect of ultrasonic vibrations on the solidification processPerform numerical modeling of the solidification processCompare data, and write and distribute final report
11 Deliverables Final report at the completion of the project Published journals in technical journal and conferencesThe reports and technical presentations will contain all detailed information (data, analysis, results, conclusions, etc.) obtained in the course of this study.
12 Condensation and Evaporation Heat Transfer in Helical Pipes HBCU/MI ETC Project 2
13 BackgroundHelical pipe condensers/evaporators attain high heat transfer efficiency.R-134a is an environmentally friendly alternative refrigerant to replace ozone-depleting R-12 for automotive and HVAC industries.Limited literature on condensation and evaporation heat transfer using R-134a in helical pipes.This project is helping DOE develop technologies that:Improve energy efficiency (cooling, refrigeration)Safeguard the environment (no ozone-depleting refrigerants)
14 ObjectivesUnderstand hydraulic and thermal behavior of refrigerant’s two-phase flow in helical pipes under various conditions (orientation, flow flux, Reynolds number, saturation temperature etc.)Develop empirical correlations for effect of operating parameters on heat transfer ratesDetermine optimal design parameters
15 Tasks Investigate gravity influence on two-phase flow (refrigerant) Investigate mass flux influence on heat transfer rate on refrigerant sideInvestigate Reynolds number influence on heat transfer rate on coolant sideInvestigate wall temperature influence on overall heat transfer rates.Investigate saturation temperature impact on heat transfer rate on refrigerant side
17 Research Approach Experimental Setup Data processing and reduction Saturation temperature automatically controlledTemperature, pressure, flow rate recorded by data acquisition systemData processing and reductionEnergy balanceNewton’s cooling lawModified Wilson Plot Techniques
18 Deliverables Annual report Papers Final report of project findings Experimental data, analysis and simulation resultsPlans for the next reporting periodPapersPublish novel research findings
