Heat Exchanger NTU-Effectiveness Calculator

Calculate heat exchanger effectiveness, NTU, and heat transfer rate using the ε-NTU method for counterflow, parallel flow, and cross-flow configurations.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How It Works

Calculate heat exchanger effectiveness, NTU, and heat transfer rate using the ε-NTU method for counterflow, parallel flow, and cross-flow configurations

Each component has a specific meaning:

  • Ε-NTU method — The ε-ntu method recorded for the patient or scenario being assessed.

Note: Interpret the heat exchanger ntu result against the clinical thresholds and context described above.

How to Use

Enter the ε-NTU method for the patient or scenario you are assessing. Calculate heat exchanger effectiveness, NTU, and heat transfer rate using the ε-NTU method for counterflow, parallel flow, and cross-flow configurations. Use the heat exchanger ntu result to inform your clinical assessment.
