Motivation & Objective
Create a CFD simulation to predict velocity gradients and pressure losses for each baffle in the flocculation tank. Use results to optimize the design of the flocculation tank.

Fall 2008 Research Proposals
- Validate which turbulence model to use. K-e realizable or K-w SST
- Calculate G_theta and compare with the theoretical data
- Analyze how energy dissipation rate is affected by Reynolds number
- Model entire flocculator instead of single baffle turning
- Explore different geometric space and achieve optimal geometry
Spring 2008 Research Goals
- Model and validate a simple 180 degree turn over two baffles:*
- Create fully second order accurate model
- Perform mesh sensitivity analysis (using coarse, medium and fine meshes)
- Model the baffles using alternate Turbulence models (K-e Standard, K-e Realizable, K-w)
- Analyze the effects of changing the baffle clearance height
- Understand and analyze the relationship between Strain Rate, Energy Dissipation and Kinematic Viscosity
- Create a flexible mesh that uses parametrization to easily change geometry dimensions
- Analyze the effect of the Reynolds Number on the results
- Analyze the sensitivity of the model to convergence residuals
- 2. Model flocculation tank and compare Simulation to Experimental results.*
