Dear Colleagues,
Separated phases in multiphase flow dictate several issues in science and technology, such as formation of flow regimes, evaporation, condensation, droplet combustion, drying, and segregation of solids.
Separated phases manifest themselves as gas-liquid, solid-liquid, or solid-gas flows. Heat and mass transfer between these separated phases remain a challenge to the multiphase flow scientists and engineers.
One of the applications is capsule flow, which adds to the economy of nations by transporting grains in pipelines. Multiphase flow intensifies the heat and mass transfer on the walls of pipes and channels.
Bubble interaction remains a subject of interest as two, three, and multi-bubbles systems need further clarification. Bubble coalescence needs further clarification in light of heat convection, mass diffusion, and surface tension.
Bubble flotation is an important industrial process of mineral separation from ores. This process requires active research to optimize the process and prevent bubble coalescence. Flash evaporation in the desalination of sea water has multiple areas that need further investigations. Direct-contact heat transfer in desalination involves the rise of volatile drops in water whereby the drops absorb heat from the body of water until reaching freezing point. This process has some ambiguities.
Gas hydrates are frozen molecules that contain the natural gas fuel molecule, called the host molecule. The shores around the US have an enormous wealth of gas hydrates that needs exploration, utilization, and new methods to supply energy to houses and buildings.
Ocean sequestration of carbon dioxide emitted from fossil-fueled power plants has the potential to decrease atmospheric CO2 concentrations. Mass transfer studies of CO2 disposal into the ocean remains to be resolved.
The research of nanofluid two-phase flow poses a challenge to understand its fundamentals.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
