Special Issue Information

Dear Colleagues,

Multiphase flows play key roles in efficient working of many renewable energy devices. Efficient water management in polymer electrolyte fuel cells, wave energy extraction from oscillation water columns, or the prevention of hail damage of solar panels depend on our understanding of complex multiphase flows. Understanding all aspects of mass, momentum, and energy exchanges under different phases in dispersed and granular flows, liquid–gas, liquid–solid, gas–solid flows, flows in porous media, and boiling phenomenon are essential for efficient renewable energy generation.

This Special Issue seeks to disseminate knowledge on various aspects of the modelling of multiphase flows relevant to renewable energy and promote multidisciplinary, fundamental, and applied research. This Special Issue aims to serve the research community by keeping them abreast of new developments in the modelling of multiphase flows relevant to renewable energy. This Special Issue covers but is not limited to the application of multiphase flows modelling in the following areas:

  1. Wave, tide, and ocean energies;
  2. Hydrogen production and fuel cells;
  3. Wind energy technologies;
  4. Solar photovoltaic and solar thermal applications;
  5. Biomass conversion;
  6. Desalination;
  7. Geothermal conversion;
  8. Desalination.

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.

In this study, advanced Computational Fluid Dynamics (CFD)-based numerical simulations have been performed in order to analyse fire propagation in a standard railway compartment. A Fire Dynamics Simulator (FDS) has been employed to mimic real world scenarios associated with fire propagation within railway carriages in order to develop safety guidelines for railway passengers. Comprehensive parametric investigations on the effects of ignition location, intensity and cabin upholstery have been carried out. It has been observed that a fire occurring near the exits of the carriage results in a lower smoke layer height, due to the local carriage geometry, than an identical fire igniting at the center of the carriage. This in turn causes the smoke density along the aisleway to vary by around 30%. Reducing the ignition energy by half has been found to restrict combustion, thus reducing smoke density and carbon exhaust gases, reducing the average temperature from 170 °C to 110 °C. Changing the material lining of the seating has been found to cause the most significant change in output parameters, despite its relative insignificance in bulk mass. A polyester sample produces a peak carbon monoxide concentration of 7500 ppm, which is 27× greater compared with nylon. This difference has been found to be due to the fire spread and propagation between fuels, signifying the polyester’s unsuitability for use in railway carriages. Full article
