Thermal & Fluids Design Optimizer
Analyze thermal systems and fluid flows with AI-powered design optimization
What You Can Do
Rapidly prototype thermal and fluid analyses, validate your design assumptions against physics-based calculations, and receive optimization recommendations from Claude acting as your design advisor. You can work through heat transfer problems, fluid dynamics scenarios, and complex multi-physics interactions without waiting for CFD simulations, accelerating your design iteration cycle significantly.
Features
Perform quick-turnaround thermal calculations for heat transfer, steady-state and transient analysis, and temperature distribution estimates without running full simulations.
Get guidance on flow rates, pressure drops, Reynolds numbers, and flow regime classification for pipes, channels, and complex geometries.
Calculate or estimate convective, radiative, and conductive heat transfer coefficients based on material properties, geometry, and operating conditions.
Receive specific suggestions for improving thermal performance through material changes, geometry modifications, or operational adjustments backed by engineering principles.
Test whether your design assumptions (flow regime, dominance of heat transfer mode, boundary conditions) are physically reasonable and identify potential issues early.
Evaluate competing design objectives—cost vs. performance, compactness vs. efficiency—and understand the engineering trade-offs involved.
Get recommendations for materials, insulation, coolants, and components based on your thermal requirements and constraints.
Example Output
Example 1: Heat Exchanger Optimization
Your Analysis:
- Inlet temps: Hot 80°C, Cold 20°C
- Duty: 50 kW
- Current LMTD: 35.4°C
Claude's Response:
✓ Estimated overall U-value: 450 W/m²K (reasonable for brazed aluminum)
✓ Required surface area: ~3.2 m²
✓ Recommendation: Counter-flow arrangement would improve LMTD to 38.1°C
✓ Bottleneck: Cold-side film resistance dominates (71% of total R-value)
✓ Action: Increase cold-side velocity or switch to higher-conductivity fluid
Example 2: Electronics Cooling Validation
Your Design:
- Component power: 150W
- Ambient: 25°C
- Target junction temp: <85°C
Claude's Analysis:
✓ Required thermal resistance: 0.4°C/W (component to ambient)
✓ Your heatsink Rth: 0.35°C/W (feasible with forced air)
✓ Risk flagged: Natural convection alone → Rth ≈ 0.8°C/W (exceeds budget)
✓ Solution pathway: Either increase airflow (0.5 m/s minimum) or upgrade sink material to copper (vs. aluminum)
Example 3: HVAC Ductwork Sizing
Your Requirement:
- Airflow: 1500 CFM to zone
- Duct length: 50 ft, 8-inch diameter
Claude's Calculation:
✓ Velocity: 8.4 ft/s (low-noise range optimal)
✓ Estimated friction loss: 0.18 in WC (within acceptable range)
✓ Re ≈ 45,000 (fully turbulent, Darcy-Weisbach applies)
✓ Warning: 6-inch duct would cause 0.45 in WC loss—likely oversizing fan
✓ Recommendation: Keep 8-inch or run parallel ductwork
