Case 1 – HVAC, Wall-mounted faceplate
SLIDE 6
Case presentation
- GOAL: Change the look
- Original design: poor flow rate
- MANDATE: GIVE DESIGN DIRECTIONS
SLIDE 7
Traditional approach
Initial Design CFD Propose alternative New Design
SLIDE 8
Revised approach
Initial Design Design Exploration Discussion Final Design

SLIDE 14
Case 2 – POOL equipment power
- ptimization
SLIDE 15
Case presentation
- GOAL: optimize power for
reduced flow/rpm
- Reduction of pump power per
new regulations
SLIDE 16
Traditional approach
1
- Fixed number of iteration
- CFD with Best-guess initial design
2
- Analyze and design next iteration
- Iterate (3 - 4 times due to cost)
3
- Prototype final design
- Hope it works in all conditions
SLIDE 17
revised approach
1
- DEFINE operation conditions
- Choose design parameters
- Explore and optimize
2
- Analyze and design next educated iteration
- Simulate new design
- Iterate if necessary
3
- Prototype final design
SLIDE 18
Optimization – initial model
- Optimate+
- Use of 3d-Cad
parameters
- 50 simulations
SLIDE 19
OPtimization- parameters
3 parameters
- Blade length
- Blade curvature
- Number of blades
Objective
- Maximize torque
SLIDE 20

3
- prototype
4
- Wind tunnel validation
SLIDE 27
revised approach
1
- Evaluate primary shapes at different angles, speed …
2
- CFD with initial design GUESS
3
- Analyze and design next iteration
- Iterate (3 - 4 times due to cost)
4
- prototype
5
- Wind tunnel validation
SLIDE 28
Example - downtube
D1 D4 D3 D2
4 parameters 2 constraints Reduce drag at:
- 0 deg
- 15 deg
- Combination
SLIDE 29
results - downtube
D1 D4 D3 D2
Results downtube
- Circular constraint AT minimum
- Min thickness at trailing edge
- 0 deg -35%
- 15 deg - 71%
- Objective - 56%
Results fork
- Less restrictions
- More complex conditions (wheel)
- Objective - 35%
