Comprehensive Heat Transfer Experiment Device
Master the determination method of the convective heat transfer coefficient αi, and deepen the understanding of its theoretical basis and influencing factors; Master the application of linear regression analysis to determine the values of constants A and m in the heat transfer correlation Nu=AR^mPr^0.4; Deepen the understanding of the basic theory of enhanced heat transfer through data comparison between threaded tubes and smooth tubes; Understand the structure of shell-and-tube heat exchangers and learn the determination methods for their heat transfer coefficients and average driving forces;
♥ 1. 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 constants A and m in the correlation Nu=AR^mPr^0.4; it can measure the vapor condensation heat transfer coefficient αo outside the tube and the overall heat transfer coefficient Ko, and compare them with the heat transfer coefficient αi inside the tube.
♥ 2. The smooth tube has a smooth cylindrical red copper tube internally and a stainless steel tube externally; the threaded tube has a threaded red copper tube internally and a stainless steel tube externally.
♥ 3. The steam generator is equipped with relevant safety measures such as a safety liquid seal, pressure sensor, and pressure alarm.
♥ 4. Capable of measuring the heat transfer coefficients of two types of sleeve heat exchangers and the heat transfer coefficient of a shell-and-tube heat exchanger.
♥ 5. Equipment appearance and dimensions: The device shall adopt a high-quality aluminum alloy frame with casters, with dimensions no larger than 2200mm×580mm×1800mm (length×width×height).
