The WL 314.03 accessory extends the experimental scope of WL 314 to include the topic: convective heat transfer inside the pipe. Convective heat transfer from the tube wall to the parallel flowing fluid is studied.
The core element of WL 314.03 is a pipe section, equipped with a heat mat to heat the outer surface of the pipe from the outside. There are six temperature measuring points in the pipe wall. A Pitot tube is used to measure the velocity distribution in the pipe cross-section.
The accessory is inserted into the air duct of WL 314 using quick-release fasteners. A fan in the air duct sucks in ambient air and conveys it through the pipe section of the accessory. The air is directed past the transfer surfaces by forced convection and heats up.
The power and surface temperature of the electric heat mat and the temperatures in the pipe wall are measured and displayed on the WL 314 trainer.
