Fluid Dynamics Simulation
Fluid Dynamics simulation is an advanced Computational engineering simulation method which is based on the study of fluid mechanics formulation. It enables CFD consulting engineers and CFD companies in Singapore to accurately model, simulate, and analysis of the fluid flow (either Liquid or Gas) behaviors created by passing through or around specific object designs. Using highly efficient computer-based Fluid Dynamics Engineering CFD Simulation software tool, it has made it possible for our CFD services to quickly Model, Simulate and efficiently Analysis fluid flow and heat transfer performance within a mechanical, electronic, or electrical systems, without the need for any complex analysis and calculation.

CFD Analysis of Acoustic Energy
Submarine air tanks are vented through-pressure ensure exhaust system composed of a valve and several ducts. The exhaust process generates high levels of sonic energy that may damage other components or present a risk for human health.
A CFD study was carried out to foresee the levels of acoustic energy generated by different designs and configurations. The information obtained was used to preselect the best designs, which were eventually tested on a test bench to confirm the conclusions met by the CAE analysis. The sonic level was eventually reduced from 400 to 100 dB.
Investigation of Gas Leakage Explosion
Authorities suspected that a gas leakage was the cause of an explosion in a building. A CFD model was built to analyze different possible scenarios and the behavior of the gas under different leakage hypothesis.
The model included the whole building, elevator shaft, ventilation ducts, underground garage and part of the street underground and public sewers. Various dispersion times and propane concentrations were analyzed.

Below is a workflow overview of our CFD consulting services at BroadTech Engineering.
1. CFD Modelling
Using 3D CAD modeling, a scale simulation model of the CFD modeling system or prototype design to be studied is created.
2. CFD Simulation
3. CFD Analysis
Computational Fluid Dynamics (CFD) analysis gives engineers a means to gain deeper insights into the prototype design performance behavior.
Base on the CFD flow analysis results obtained from the CFD fluid dynamic simulation, it makes it possible to
1. Test & Validate New Design
CFD simulation enables the subjecting of the prototype design to various usage scenarios in a virtual simulation environment without the need for any actual prototype testing, physical test, or time-consuming cyclic endurance testing.
2. Identify Flow Concentration Hotspots
Analyze Airflow dynamics & thermal distribution, to identify and investigate any pressure hotspot areas via the use of CFD thermal analysis.
eg. Helps ESD consultants and Green Building consultants to optimize Building aerodynamics for natural wind ventilation.
3. Refine & Optimize Design without Physical Prototyping
Optimize prototype design to strike a balance between various opposing related parameters, such as
eg. equipment power requirements and Equipment safety
Through the testing and validation of various design iteration in a digital simulation environment, it allows engineers to refine their design to get their detailed designs right the 1st time even before the first actual prototype is being fabricated & tested physically.

Features & Benefits of Fluid Dynamics Simulation
1. Early Engineering Insights During Design Phase
Fluid Dynamics Simulation offers the benefit of removing the complexity out of fluid flow analysis by allowing you to easily calculate fluid forces and understand the impact of a design decision on product performance in a liquid or gas medium.
Engineering Simulation as A Replacement for Physical Testing
When the power of Fluid Dynamics is incorporated into a regular component of your engineering design workflow, it effectively eliminates the need for the actual fabrication and testing of physical prototypes.
This helps to save time and money and accelerate the rate of innovation.
2. Cost Savings in Engineering Development
As the engineering Simulation is incorporated early in the engineering design process, the computational fluid analysis makes it possible for engineers to identify and quickly rectify any potential design problems early in the development process.
This helps to prevent the design issues from discovered too late in the engineering development process, such as during pre-production, where any design change will involve serious project schedule delays and costly tooling re-work, which can easily cost thousands of dollars.
Overall Computational Fluid dynamics simulation helps to help our clients save precious project man-hours and development cost.
3. Practical Industrial Benefits
The use of Computational Fluid Dynamics (CFD) simulation can virtually benefit all Engineering companies in a broad range of industries, such as Aerospace engineering, Automotive manufacturer, Bio life science, Defense Technology and Industrial Machinery.

Conclusions
- The Gurney flap increased blade loading and the torque produced.
- A pair of counter-rotating vortex was generated behind the trailing edge that modified the trailing edge Kutta condition which increased circulation and lifts. At a higher angle of attack, the counter-rotating vortex pair collapsed, and the aerodynamic benefit of the flap was diminished.
- A flap of 0.5% chord length enhanced the relative average torque produced by 10.7% with a decrement in relative average efficiency by 4.7% before stall condition.
- A flap height greater than 1.5% chord length advanced the stall and reduced the operating range.
- The above results from the Wind Load Analysis are published in the peer-reviewed journal “Ocean Engineering”.
