There is a linear relationship between the flow patterns of a bubble swarm and heat transfer
from the viewpoint of experimental analysis. To investigate the space–time features of the …

The study of bubble swarm distributions in a direct-contact heat exchanger was addressed
both theoretically and experimentally. But recently developed approach based on uniform …

This paper presents a straightforward method for assessing the uniformity and mixing time of
bubbles based on uniform design in a direct contact heat exchanger. The evolution of …

To address the problem of large differences in the mixing time calculated by different
characterization methods, this paper proposes an average distance (AD) method, a novel …

As the binary image fails to reflect the density distribution of the bubble, this paper proposes
an improved new indicator for accurate measurement of spatial uniformity based on gray …

This paper proposes a novel method to quantify the synergy of bubble swarm patterns and
heat transfer performance in a direct-contact heat exchanger (DCHE) by using …

By bringing two immiscible fluids at different temperatures into a direct contact heat
exchanger (DCHE), bubble swarms are produced in the dual-loop ORC direct contact …

In this work, a combination of morphological processing and watershed algorithm is
proposed to measure bubble size, based on which an improved frame difference method is …

In the present study, a new method is proposed to measure the uniformity of temperature
distribution and the phase distribution in direct contact boiling heat transfer. The proposed …

A new index, the estimate of the error variance, which can be used to quantify the evolution
of the flow patterns when multiphase components or tracers are difficultly distinguishable …
