45° or 90° Square Patterns: Best for heavily fouling fluids (fouling resistance
30° Triangular Pattern: Offers the highest tube density and heat transfer coefficients, making it the most cost-effective per m2m squared . Note: These cannot be mechanically cleaned. htri heat exchanger design top

Top-tier HTRI design involves analyzing the Wall Temperature output tab. If the wall temperature is approaching the pour point or cloud point of the fluid, you aren't solving fouling; you are inviting it. You must balance the $R_f$ with velocity. High velocity (high shear) cleans the tubes; high surface area (low velocity) lets dirt settle. The HTRI designer must choose shear over area.
The "top" designs focus heavily on the shell side, where pressure drop and heat transfer are hardest to predict. HTRI (Heat Transfer Research, Inc
As the industry shifts toward sustainability, HTRI is evolving. Modern designs now focus heavily on Process Intensification—getting more heat transfer out of smaller, more efficient units. This reduces the carbon footprint of manufacturing plants by lowering material usage and energy consumption.
3. Two-Phase Flow: The "Flow Regime" Map
In single-phase flow, the fluid behaves. In two-phase (boiling or condensing), the fluid riots. This is where HTRI’s proprietary correlations shine, but they require interpretation. Collaborate with HTRI Experts : Work closely with
Step 7: Economic Optimization
The largest area does not equal the "top" design. Run a lifecycle cost analysis using HTRI’s Cost Estimation feature (or export to a separate tool).
