GUNT Under real conditions, heat transport between two objects involves both substance-bound processes like convection and conduction, and non-substance-bound processes such as radiation. The GUNT trainer enables separation and analysis of heat quantities associated with each type of transfer.
Product Features
- Core element is a heated metal cylinder at the center of a pressure vessel with controlled surface temperature
- Temperature sensors measure the surface temperature of the metal cylinder and the pressure vessel wall
- Study of heat transport from the metal cylinder to the pressure vessel wall under various conditions
- Pressure vessel can be evacuated to vacuum or pressurized with gas to simulate different heat transfer modes
- Vacuum conditions isolate radiation as the primary heat transfer mode
- Positive gauge pressure with gases like air, nitrogen, helium, carbon dioxide allows study of convective heat transfer
- Heat conduction is minimized by suspending the metal cylinder appropriately
- Rotary vane pump generates vacuum down to approximately 0.02 mbar
- Positive gauge pressures up to about 1 bar achievable with compressed air
- Pressure measured by two sensors: Pirani sensor for vacuum and piezo-resistive sensor for positive pressure
- Digital displays show real-time measurement values
- USB data transmission to PC with included GUNT software for detailed analysis
