Model & approach
- Compare baseline, extended hood and hood-with-openings variants
- Model an open configuration as a theoretical reference
- Assess airflow, pressure buildup and thermal fields
Project / Construction machinery
Cooling concepts for a compressed-air conveyor
Four enclosure variants exposed how hood volume and openings affected airflow, pressure loss and temperature while the design was still fluid.
Engineering question
A new unit needed a safe cooling concept for hot ambient operation before the physical enclosure was fixed.
Boundary conditions
- Thermally demanding example operating condition
- Motor, compressor and coolers as thermal components
- Four enclosure states
Results of the assessment
- The baseline enclosure restricted airflow.
- A larger hood increased the available flow volume.
- Strategically positioned openings offered another design lever.
Engineering consequence
Concept selection could focus on hood length and the position of inlet and outlet openings.
Context
The study supported concept selection using the calculated flow field.
