Heat Transfer

Welcome to the Heat Transfer Laboratory!

Our Heat Transfer Lab is a well-equipped facility designed to provide in-depth, practical exposure to the principles of heat transfer. This laboratory enables students to explore conduction, convection, and radiation through hands-on experiments using modern and industrial-grade equipment.

Laboratory Infrastructure

1. Comprehensive Equipment
   • Thermal Conductivity Apparatus: For solids and liquids to study one-dimensional steady-state conduction.
   • Pin-Fin Apparatus: Analyse heat dissipation using extended surfaces.
   • Forced Convection Apparatus: Study heat transfer in a duct with air flow.
   • Natural Convection Apparatus: Examine vertical surface heat transfer due to buoyancy effects.
   • Stefan-Boltzmann Apparatus: Explore the radiation laws and black-body behavior.
   • Emissivity Measurement Setup: Compare radiative properties of different surfaces.
   • Heat Exchangers (Parallel and Counterflow): Understand heat transfer effectiveness in fluid systems.
   • Composite Wall Apparatus: Investigate conduction through multi-layered materials.
2. Hands-on Learning
   • Investigate conduction, convection, and radiation processes.
   • Understand the thermal behavior of materials under various conditions.
   • Use real-time data acquisition systems for accurate thermal analysis.
   • Analyze and interpret experimental results using theory and empirical correlations.
3. Prototyping and Testing
   • Adjust input power, fluid flow rates, or ambient conditions to test variables.
   • Calculate heat transfer coefficients, efficiency, emissivity, and performance indices.
   • Visualize temperature gradients and learn transient vs. steady-state analysis.
