Numerical Modeling and Optimization of Fluid Flow in Engines

Dear Colleagues,

The internal flow within engines exhibits complex multi-process coupling effects. Current research still lacks a comprehensive understanding of these internal flow characteristics and their interaction mechanisms. These limitations result in insufficient capabilities for monitoring and controlling multi-mode flow conditions, which emphasizes the necessity for deeper investigation into complex flow behaviors and fundamental physical mechanisms within engines. The accurate simulation and optimization of engine flows will enhance understanding of fluid dynamics within engines, leading to more efficient combustion processes, reduced emissions, and improved engine performance. Optimizing fluid flow processes in engines positively contributes to energy efficiency enhancement, sustainable transportation development, and environmental protection.

This Special Issue of Processes covers research on the numerical modeling and optimization of fluid flow in engines. Research topics include, but are not limited to, aeroengines, ramjets, scramjets, variable cycle engines, precooled engines, RBCCs, and TBCCs. The research includes internal flow mechanisms, data-driven modeling aerodynamics, and flow control of the engines.

The topics of the Special Issue include, but are not limited to, the following:

• Shock wave/boundary layer interaction;
• Shock wave/vortex coupling interference;
• Supersonic turbulent flow for chemical equilibrium;
• Flow controlled supersonic flow;
• Supersonic rocket nozzle flow;
• Supersonic impinging jet flow;
• Shock wave aerothermal and drag reduction;
• Shock wave/combustion interaction;
• Flow control methods;
• Wind tunnel experimental methods;
• Numerical calculation methods;
• Flow field prediction;
• Machine learning in flow modeling and flow control;
• Flow field feature extraction;
• Fusion method of multi-source aerodynamic data;
• Non-Equilibrium thermodynamics;
• Dynamic modeling;
• Reduced-order modeling;
• Integrated propulsion–airframe design;
• Inlet-Engine matching control.

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. Processes is an international peer-reviewed open access monthly 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 2400 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.
