On December 9, Professor Hu Longhua from the University of Science and Technology of China was invited to our university to give an academic report titled "Scale Effects of Fire Combustion and Flame Instabilities under Environmental Wind, Low Pressure, and Micro/Hypergravity Conditions," and to exchange ideas on grant applications. Faculty and students from related departments attended the report. The meeting was chaired by Professor Pan Jianfeng, Dean of the School of Energy and Power Engineering.

Professor Hu Longhua shared the research progress and achievements of his team in fire dynamics, introducing issues related to fire combustion scale effects, flame propagation, and flame extinguishing instabilities, which are classic scientific questions in the field of fire and combustion science. Under special conditions such as environmental wind, low pressure, and micro/hypergravity, the heat transfer behavior in diffusion flames, turbulence intensity of the flow field, and its interaction with thermal buoyancy can have complex effects on the flame structure and stability. Through decades of theoretical and experimental research, Professor Hu's team has made significant progress on these cutting-edge issues, providing valuable academic results for the further development of fire science.

After the report, Professor Hu engaged in in-depth exchanges and discussions with attendees, sharing directions and challenges for future research. This academic report not only enhanced the understanding of frontier issues in fire science among faculty and students but also provided valuable insights for researchers in related fields.
