Motivation & Objective

...

Johannes Haarhoff and Jeremia J. van der Walt , J Water SRT - Aqua 50 (2001) 149-160 - - Towards optimal design parameters for around-the-end hydraulic flocculators.

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

• 1. 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.*
