Special Issue Information

Dear Colleagues,

As the global demand for energy continues its upward trajectory, the imperative to develop sustainable and efficient energy utilization processes has become increasingly pressing. In this context, the understanding and optimization of transfer processes, encompassing fluid dynamics, heat transfer, and mass transport, emerge as pivotal elements of paramount importance in the pursuit of a cleaner and more sustainable energy landscape.

This Special Issue endeavors to explore new research in the realm of flow, heat, and mass transfer processes in energy utilization. Through a collection of diverse contributions, we seek to unravel the complexities existing in the strong coupling of fluid, heat, and mass transfer processes, offer insights into novel approaches, and provide a platform for discussions that will shape the future of energy utilization. By fostering collaboration and knowledge exchange, we aspire to contribute to a sustainable and resilient energy future that meets the needs of the present without compromising the needs of future generations.

The problem of particle clogging in a conveying pipeline in thin-phase pneumatic transportation is essentially the effect of the particle-deposition mechanism in gas–solid two-phase flow. This paper presents a particle-deposition model of gas–solid two-phase flow based on the ellipsoid hypothesis, and a fast-calculation method of material particle-deposition efficiency in industry based on the tabular-assigned drag-correction coefficient of the particle ellipsoid-shape parameter Ar and incoming flow angle ϕ. A simulation comparison of spherical particles under the same pneumatic transport conditions and experimental verification based on the self-built particle deposition system are given. The validity of the model and the accuracy of the algorithm are verified. This provides a feasible simulation and experimental scheme for the research of pneumatic-conveying technology in the industrial field. Full article

Heat-transfer enhancement and entropy generation were investigated for a double-helical-type-channel heat sink with different rib structures set on the upper wall. Based on available experimental data, a series of simulations with various turbulence models were conducted to find the best numerical model. Five different rib structures were considered, which were diamond (FC-DR), rectangular (FC-RR), drop-shaped (FC-DSR), elliptic (FC-ER) and frustum (FC-FR). The research was carried out under turbulent flow circumstances with a Reynolds number range of 10,000–60,000 and a constant heat-flow density. The numerical results show that the thermal performance of the flow channel set with a rib structure is better than that of the smooth channel. FC-ER offers the lowest average temperature and the highest temperature uniformity, with a Nusselt number improvement percentage ranging from 15.80% to 30.77%. Overall, FC-ER shows the most excellent performance evaluation criteria and lowest augmentation entropy-generation number compared with the other reinforced flow channels. Full article
