Mixing is a ubiquitous operation in process engineering. It is not only used for combining
materials, but also for promoting heat and mass transfer, increasing aeration, suspending …

Heat dissipation in high-heat flux micro-devices has become a pressing issue. One of the
most effective methods for removing the high heat load of micro-devices is boiling heat …

Direct contact heat exchangers can be smaller, cheaper, and have simpler construction than
the surface, shell, or tube heat exchangers of the same capacity and can operate in …

The paper deals with the classification and the design features of direct contact heat
exchangers used in various technological processes. It describes the existing two-phase …

The pattern complexity (kinetics and uniformity) of bubble swarms governs the heat transfer
performance in gas-liquid contact systems such as direct-contact boiling heat transfer …

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 …

The measurement of the two-phase contact area is very important to determine the heat
transfer coefficient in the process of direct contact heat transfer, but the direct measurement …

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 …

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 …

Direct-contact heat exchangers have great potential for waste-heat utilization. This study
established a multi-objective evaluation model of the volumetric heat-transfer coefficient …
