Recently, our turbulence research team published a research paper titled "Heat Transfer and Energy Evolution in Compressed Flow Around a Locally Heated Cylinder" in the authoritative international journal in the field of heat transfer, International Journal of Heat and Mass Transfer (JCR Zone 1, Impact Factor 5.2).

As a key project of the National Natural Science Foundation of China, this study focuses on the thermodynamic behavior and energy evolution mechanism of compressible locally heated cylinder flow. Based on high-precision numerical simulation data, the research team innovatively combined methods such as pseudo vortex energy analysis and time averaged total enthalpy transport equation to deeply explore the influence of different heating positions on the evolution of flow field vortex structure, heat transfer characteristics, and aerodynamic characteristics. For the first time, the characteristic regions of total enthalpy changes in the near wake region of a heated circular cylinder were accurately captured, and the physical mechanisms formed by different characteristic regions were quantitatively analyzed. This discovery provides a key theoretical basis for the design and performance optimization of local heating components such as surface sensors and airspeed tubes in the aerospace field.

The research results not only deepen the understanding of heat and mass transfer mechanisms in complex flows, but also mark a new level of research on key issues in related fields by our turbulence research team. It has important scientific significance for promoting the breakthrough and innovative development of key technologies in major engineering projects. Professor Liu Yulu is the first author of the paper, with Tao Yizhou and Qiu Xiang as corresponding authors, and graduate students such as Gao Shulong and Zou Fan also participated in the research work.
