About Heat Transfer At A Cylinder In Transverse Flow

HEAT TRANSFER AT A CYLINDER IN TRANSVERSE FLOW

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 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 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 software.

Part of a series that allows experiments on the principles of incompressible air flow. The software for data acquisition and visualisation makes the experiments especially clear and enables fast execution of experiments with reliable results.

The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
