TH105 Extended Surface Heat Transfer
Overview
The TH105 Extended Surface Heat Transfer Experiment Module is designed to measure the temperature distribution and heat transfer along a horizontally extending surface (cylindrical rod). A small diameter uniform bar is heated at one end and heat is transferred to the other end by thermal conduction, during which a portion of the heat is lost to the surrounding environment by a combination of natural convection and radiative heat transfer. The resulting heat transfer can be studied by conventional analysis and the temperature distribution can be predicted.
Features
• Demonstrates heat transfer by combined natural convection and radiation.
• Measures steady-state temperature distribution along a cylindrical brass bar.
• Includes a solid, matte black brass specimen heated at one end..
• Equipped with multiple thermocouples for precise temperature profiling.
• Allows calculation of metal thermal conductivity using a circular fin model.
• Records ambient temperature for accurate heat loss analysis.Specifications
