WL 220

Boiling Heat Transfer Unit

Technical Description

The transparent process tank makes it possible to clearly observe the evaporation process at the heated cylinder. The cylinder is used as a model to demonstrate a fire tube heated from the inside. An integrated water-cooled condenser allows for a continuous boiling process. The special liquid used evaporates at low temperatures. Sensors provide all relevant data. The measured values are indicated on digital displays and can also be transmitted directly to a PC. A data acquisition card and software are included.
A supply of water is required.

Learning Objectives / Experiments

- Different forms of evaporation (nucleate, film
boiling)
- Heat transfer coefficient
- Effect of temperature and pressure on the
evaporation process
