The Labtronic Combined Heat Transfer Trainer (LT-HT105) is a compact and versatile teaching tool designed to demonstrate the fundamental modes of heat transfer, including conduction, convection, and radiation. This unit allows students and researchers to explore the interactions between convection and radiation, providing a comprehensive understanding of combined heat transfer processes.
1. Combined Heat Transfer Measurement:
- Investigate the combined heat transfer (Q_radiation + Q_convection) from a horizontal cylinder via natural convection.
- Explore various power inputs and corresponding surface temperatures to understand the behaviour of heat transfer under different conditions.
2. Dominant Heat Transfer Coefficients:
- Analyze how the convective heat transfer coefficient (Hc) dominates at lower surface temperatures and how the radiation heat transfer coefficient (Hr) becomes more significant at higher surface temperatures.
- Gain insights into the factors that govern different heat transfer modes and their interactions.
3. Forced Convection Effects:
- Examine the effects of forced convection on heat transfer from the cylinder at varying air velocities.
- Understand the impact of air movement on heat transfer dynamics and identify the interplay between convection and radiation.
