Three-Tube Heat Transfer Educational Pilot Plant for Unit Operations Training

Introduction

The Three-Tube Heat Transfer Educational Unit Operations Pilot Plant is an integrated laboratory training system designed for engineering students to investigate convective heat transfer mechanisms and vapor condensation principles. Featuring three distinct tube configurations—smooth, corrugated, and turbulent—the system provides a practical platform for comparative analysis of heat transfer enhancement techniques and condensation phenomena. This unit is developed to align with core laboratory syllabi and support engineering education accreditation by translating theoretical thermodynamic principles into observable physical processes.

To accommodate varying laboratory spaces, experimental curricula, and technological infrastructures, this pilot plant features a flexible design. Both the hardware components and the software interface can be customized to meet the specific pedagogical and technical requirements of your institution.

Key Teaching Functions and Advantages

• Comparative Analysis of Heat Transfer Enhancement: Allows students to measure and compare the heat transfer coefficients of three distinct pipe designs under identical operational parameters, highlighting the engineering trade-offs of modern heat exchanger design.
• Empirical Correlation Verification: Facilitates the direct determination of constants $A$ and $m$ in the convective heat transfer correlation $Nu=ARe^mPr^{0.4}$ inside circular straight tubes.
• Vapor Condensation Evaluation: Enables the determination of the overall heat transfer coefficient ($K_o$) and the external vapor condensation heat transfer coefficient ($\alpha_o$), providing a quantitative comparison with the internal convective heat transfer coefficient ($\alpha_i$).
• Visual Study of Condensation Mechanisms: Provides clear visual monitoring to help students distinguish between filmwise condensation and dropwise condensation on various outer tube surfaces.
• Eco-Friendly and Closed-Loop Operation: Features a steam condensate recovery loop that recaptures vented steam, eliminating the need for continuous distilled water replenishment and reducing utility consumption during lab sessions.
• Multi-Tiered Safety Systems: Built with essential safety measures including a mechanical water seal, integrated pressure sensors, and automatic overpressure alarms to ensure a reliable learning environment.
