Special Issue Information

Dear Colleagues,

The Guest Editor is inviting submissions to a Special Issue of Energies titled “Numerical Investigation of Heat & Mass Transfer in Reacting Hydrocarbon Flows for Aerospace Energy Conversion”. Managing the complex multiphysics and transient phenomena involved in the cooling strategies applied to aerospace structures is a necessity, and numerical simulation is now largely used for accessing multidimensional and multiscale analysis which is impossible to perform experimentally. Gathering key international key studies in the same Special Issue enables us to deliver a broad overview of current and ongoing activities in this challenging field. This Special Issue will deal with novel investigations which are nowadays at the forefront of frontier activities in high-speed flight. Topics of interest for publication include, but are not limited to:

  • Design of cooling channel;
  • Coke formation;
  • Heat transfer coefficient;
  • Flow distribution;
  • Energy distribution;
  • Fuel pyrolysis;
  • Thermo-mechanical effects;
  • Control and optimization.

Steam reforming is an effective method for improving heat sinks of hypersonic aircraft at high flight Mach numbers. However, unlike the industrial process of producing hydrogen with a high water content, the catalytic steam reforming mechanism for the regeneration cooling process of hydrocarbon fuels with a water content below 30% is still unclear. Catalytic steam reforming (CSR) and catalytic thermal cracking (CTC) reactions occur at low temperatures, with the main products being hydrogen and carbon oxides. Thermal cracking (TC) reactions occur at high temperatures, with the main products being alkanes and alkenes. The above reaction exists simultaneously in the regeneration cooling channel, which is referred to as partial catalytic steam reforming (PCSR). Based on the experimental measurement results, an improved neural network correction method was used to establish a four-step global reaction model for the PCSR of n-decane under low water conditions. The reliability of the four-step model was verified by combining the model with a numerical simulation program and comparing it with the experimental results obtained by electric heating hydrocarbon fuels with a pressure of 3 MPa and a water content of 5/10/15%. The experimental and predicted results using the developed kinetic model are consistent with an error of less than 5% in the decane conversion rate. The average absolute error between the fuel outlet temperature and total heat sink is less than 10%. Using the PCSR model to predict the heat transfer characteristics of mixed fuels with different water contents, the convective heat transfer coefficient is basically the same, and the Nu number is affected by the thermal conductivity coefficient, showing different patterns with changes in the water content.
