Hydrodynamic Simulations

Hydrodynamics Simulation is often used by the Marine Industry in Singapore to optimize the Ship design.
This helps to operationally make the Ship design more energy-efficient and boosts its performance reliability.
Numerical Ship Optimization and Computational Ship Hydrodynamics simulation has important application in various aspects of Ship design, such as
  1. Marine Green Water Loading
  2. Marine Ship Trim Optimization and Ship Draft Optimization Studies
  3. Marine Ship Propeller simulation performed using Hydrodynamic Simulation
  4. Marine Propeller Cavitation CFD Simulation to minimize Corrosion at high-speed RPM
  5. Marine Ship Hull Design Optimization to minimize Drag resistance which can lower fuel efficiency

CFD Hydrodynamic Simulation of Flotation tank and Flow Control Valves

 

BroadTech Engineering was tasked as the CFD Services company for this CFD Consulting project.
A bank of settling tanks was analyzed using CFD simulation to determine the correct sizing of flow valves and the height of the outlet back-pressure pipe for required flow characteristics between tanks. The design was approved by the time our CFD Consultant finished his contract with the company (short-term contract).
 
Thermal-hydraulic analysis of sinusoidal fin-based printed circuit heat exchangers for supercritical CO2 Brayton cycle
BroadTech Engineering was tasked as the CFD Consulting company for this CFD Consulting project, where we would be providing professional CFD Analysis Services.
Simulation Objectives
  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

Channel geometry was proposed by our CFD Engineer at our Fluid Dynamics Company to minimize the pressure losses across the PCHE is based on the sinusoidal fins placed in a staggered arrangement.
Initially, the performance of both channel geometries i.e., proposed channel geometry and the conventional zigzag channel geometry, were computed numerically using CFD Thermal Analysis and compared.
Later, an optimization CFD Flow Simulation study of the channel geometry was carried out based on four geometric parameters using response surface methodology (RSM) along with the genetic algorithm.
To facilitate RSM with the input data used for the CFD Modeling Services provided to the Client, central composite design (CCD) was employed for the design of experiments while the output was computed using 3D RANS simulation coupled with the Computational Fluid Flow Simulation.
Once channel geometry was optimized, the performance of the optimized channel geometry was computed for a wide range of the Reynolds number based on which heat transfer and pressure drop correlations were developed.
 

Outcomes & Conclusion

Based on the conducted CFD Consulting study, the following deductions have been made:
  • 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
 
 

 

Hydrodynamic extensional stress during the bubble bursting process for bioreactor system design

 

Simulation objective:

BroadTech Engineering was a task as the CFD Company to perform CFD flow Analysis and Numerical modeling to predict extensional stress as a function of the bubble diameter and the surface tension.
 

Methodology:

Coupled level-set and volume-of-fluid methods are used during the CFD Consultancy project to simulate multiphase flow in commercial ANSYS FLUENT software.
 

Outcome and Conclusion:

As part of the scope of work for the CFD Consulting services rendered to the client, the extensional stress estimation is reported as a function of the bubble size and the surface tension.
During the process of the CFD Modeling, the influence of the bubble size on the maximum stress dominates and extensional stress reaches up to the order of 10^4 Pa for bubble size of 0.5
