Supersonic Fluid Flow Process and Its Control Methods

Dear Colleagues,

Supersonic fluid flow refers to the phenomenon of fluid flowing at a speed exceeding the local speed of sound. Different from subsonic flow, complex phenomenon of shock wave/boundary layer interaction occurs during the flow of supersonic fluid. Shock wave, as a type of highly discontinuous flow field, cause abrupt changes in density, temperature, and velocity in the flow field before and after the shock. The boundary layer along the wall, as a typical low-speed shear layer, also exhibits significant variations in physical quantities along the normal direction to the wall. Both of them are gradient fields of physical quantities, but their strengths and directions of effects are different. It is precisely because of these similarities and differences between shock wave and boundary layer that the interaction between them becomes exceptionally complex. It is a key and challenging issue that must be considered in aircraft design. The related research involves fundamental issues such as high-speed aerodynamics, flow stability, transition, separation, turbulence, and flow control. It belongs to the forefront of aerodynamics research.

Based on this, it is planned to create a Special Issue on “Supersonic fluid flow process and its control methods”. Through this, the aim is to enhance the understanding of the flow mechanism of supersonic fluid flow process, develop flow control methods to improve the flow field quality, and promote the improvement of aerodynamic performance of air-breathing hypersonic vehicles. This Special Issue focuses on the shock wave/boundary layer interaction, shock wave/vortex coupling interference, supersonic turbulent flow for chemical equilibrium, flow controlled supersonic flow, supersonic rocket nozzle flow, and other areas.

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

• 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

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.
