Abstract

Abstract

Liquid-gas two phase flow can be characterized by its flow pattern signals, which are offen with some random noises. A general two phase flow experimental facility is set up to obtain flow pattern signals in two phase flow pipes. Flowing signals are decomposed with Daubechies wavelets to differ the noises from flow pattern signals. The denoised signals are quite well after reconstruction.
