Description

The aim of this basic experiment is to determine the heat transfer coefficients, a specific indicator, from the cooling curve. Cooling curves describe the temperature compensation between a body and its surroundings, as a function of time.
Used in conjunction with principle of air flow, the accessory makes it possible to record the cooling curve of a cylinder in air flow. The accessory includes an oven and a copper cylinder. The large copper cylinder is heated in the oven to approximately 120°C. Then, the heated cylinder is placed in principle of air flow’s intake pipe and cooled in an air flow.
A temperature sensor is fitted inside the cylinder. The convective heat transfer on the cylinder can be determined from the cooling rate.
The experiment can be performed for various flow rates. The measured values are analysed using the principle of air flow software.
