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.

Semester 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.*
