CFD Hydrodynamic Simulation of Flotation tank and Flow Control Valves

1. Design a new channel geometry using CFD Design Methods to enhance the hydraulic performance of the PCHEs.
2. Optimization of the proposed channel geometry using Computational Fluid Dynamics Simulation to maximize its PEC (Performance Evaluation Criteria)
3. To use CFD Thermal Analysis to Facilitate the Development of the heat transfer and pressure drop correlations for the proposed channel geometry

Methodology and Approaches Used

Outcomes & Conclusion

• Results from the CFD Analysis reveal that the hydraulic performance could be improved appreciably by replacing the zigzag channel geometry with the proposed channel geometry based on the sinusoidal fins. For the proposed channel geometry, the pressure drop factor (or pressure drop itself) is up to 2.4 times smaller in comparison with the conventional zigzag channel geometry.
• Overall performance comparison of the proposed fin and conventional zigzag geometry based on the PEC shows that the former exhibit superior performance at lower values of the Reynolds number but at higher values of the Reynolds number its performance deteriorates since the thermal performance of the proposed fin geometry degrades at higher Reynolds number.
• Channel optimization results from the CFD Modeling demonstrate that optimized channel geometry exhibits better performance for both lower and higher Reynolds numbers in comparison with the conventional zigzag channels.
• For the optimized channel geometry, the maximum values of the PEC (1.21 for the cold side and 1.16 for the hot side) correspond to the minimum value of the Reynolds number. While the minimum values of the PEC (1.02 for the cold side and 1.01 for the hot side) correspond to the maximum value of the Reynolds number.
  This CFD Services rendered during the CFD Research and Consultancy Project demonstrates that optimized channel geometry exhibits better performance for both lower and higher Reynolds numbers in comparison with the conventional zigzag channels
