Three – Tube Heat Transfer Experiment Device
The device features professionalism, aligning with teaching syllabi and designing educational content that meets the requirements of engineering education accreditation: It can verify the empirical correlation for enhanced convective heat transfer in circular straight tubes, determining the values of constants A and m in the correlation Nu=AR^mPr^0.4; understand the vapor condensation heat transfer coefficient outside the tube (αo) and the overall heat transfer coefficient (Ko), and compare them with the heat transfer coefficient inside the tube (αi); and gain knowledge of the phenomena of dropwise condensation and filmwise condensation.
♥ 1. The device is rich in content: it can measure the heat transfer coefficients of smooth tubes, corrugated tubes, and turbulent tubes;
♥ 2. It can measure the vapor condensation heat transfer coefficient outside the tube (αo) and the overall heat transfer coefficient (Ko);
♥ 3. The device allows observing the vapor condensation conditions outside different heat exchange tubes;
♥ 4. The steam condensate in the device can be cyclically recovered, including condensate recovery after steam venting, and the steam generator does not require adding distilled water;
♥ 5. The device is safe: the steam generator used in the device fully considers safety factors, and is equipped with relevant safety measures such as a safety water seal, pressure sensor, and pressure alarm;
♥ 6. Equipment appearance and dimensions: The device is required to adopt a high-quality aluminum alloy frame with casters, with dimensions no larger than 2200mm×580mm×1880mm (length×width×height).
