Special Issue Information
Dear Colleagues,
The demand for higher efficiency of gas engine brings the need of higher turbine inlet temperature (TIT) and lower specific fuel consumption (SFC), which makes cooling and sealing technology very important. The development of these two technologies integrates multiple discipline such as fluid mechanics, heat transfer, thermodynamics, material, etc. With the continuous upgrading of gas turbines, more studies are focused on the cooling and sealing technology including higher cooling and sealing efficiency, lower loss, more optimized structures and less secondary air, which needs concept innovation, fundamental intensification, methodology improvement, and application validation.
This Special Issue aims to present and disseminate the most recent advances related to the theory, design, modelling, measurement, optimization, application for gas turbine heat transfer.
Topics of interest for publication include, but are not limited to, the following:
- All aspects of heat transfer in gas turbines.
- Cooling technology for gas turbines including film cooling, transpiration cooling, impingement cooling, double-wall cooling, rib, pin-fin, etc.
- Flow and heat transfer for rotating cavity.
- Flow and heat transfer for pre-swirl system.
- Sealing technology for gas turbine including labyrinth seal, brush seal, carbon seal, finger seal, film seal, rim seal, etc.
- Mixing mechanism between leakage flow and cooling flow.
- AI optimization.
- Advanced modelling approaches.
- Advanced measurement methods.
- Thermal management.
- Secondary air system.

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.
