Special Topic on Selected Papers from the 11th National Congress on Fluid Mechanics of China.

Yu I et al. i [1] presented an interesting investigation on the flow and aerodynamic heating characteristics of air and hydrogen-oxygen combustion gas under the same total temperature and pressure. The authors concentrated on the variations of temperature and velocity of the combustion gas flow in a nozzle and the shock standoff distance and stagnation pressure for the combustion gas flows around a sphere. Fluid mechanics covers a vast scope of flow phenomena that occur in nature, biology, and numerous engineering fields. [Extracted from the article]
