Experimental study of gravity heat pipe with ECT
Gravity heat pipes interior phase change and heat transfer mechanisms are hardly to research, yet significant for strengthening heat transfer and enhancing energy utilization. This paper reports experimental study on the reconstructed images and concentration measurement of liquid (ethanol) at condensation section of gravity heat pipe with electrical capacitance tomography (ECT). Furthermore, signals noises collected by ECT have been reduced with Hilbert-Huang transform (HHT). Finally, reconstruction images have been compared with M. Shiraishs model, and ECT has provided alternative experimental platform for the research of gravity heat pipes mechanisms.
