Hello everyone, my name is Muhammad Ikhsan Rahadian from mechanical engineering 2021. Allow me to share my result for Sustainable Energy Conversion System assignment.
By using SimScale software, I was able to predict the airflow of a 5 floor building .

Analysis:
1. Wind Flow Patterns
- The streamlines show how air moves around the building.
- Wind accelerates over the top and sides, creating high-velocity zones (yellow and green streamlines).
- A recirculation zone is observed behind the building, indicating possible turbulence and lower wind speeds.
2. Pressure Distribution
- The front face of the building experiences higher pressure (yellow/red areas), leading to wind resistance.
- The leeward side (back of the building) has lower pressure (blue regions), which may cause wind eddies and vortex shedding.
- Negative pressure zones behind the structure could influence ventilation and pollutant dispersion.
3. Velocity Analysis
- Wind acceleration zones: Higher velocity magnitudes (yellow-green areas) suggest strong wind forces near building edges.
- Wind stagnation zones: Lower velocities (blue) indicate areas of reduced airflow, affecting comfort levels and heat dissipation.
- Near-ground wind speeds: Understanding this helps assess pedestrian wind comfort and thermal comfort.
4. Impact on Microclimate
- Ventilation Efficiency: Low-pressure zones might trap pollutants or heat, impacting air quality.
- Thermal Comfort: Poorly ventilated areas could lead to heat buildup, especially in urban settings.
