Pool boiling experiment characteristics on the pure copper surface

The pool boiling characteristics with different boiling surfaces and working fluids play an important part in multiphase flow research. The key parameters of pool boiling, such as heat transfer coefficient (HTC) and critical heat flux (CHF), can be only acquired by experiment. Thus, a pool boiling experimental device is designed and produces the HTC and CHF data on the pure copper heating surface, which are 72.25 kW/(m²·K) and 1093.28 kW/m², respectively. Besides, a series of visualization experimental results of bubble behavior in the pool boiling are taken by the high-speed camera to provide references for the boiling mechanism research. The pool boiling experiment would be the benchmark data to validate the future experiments and computer simulations.
