: Acoustic response from a freely responding symmetric airfoil subjected to gust is investigated in a two-dimensional numerical environment. Gust model is superimposed on the inlet velocity up till the critical flutter velocity. Second order transient formulation, k − ω turbulence model and dynamic meshing technique were adopted. By employing the Ffowcs Williams and Hawkings (FW-H) acoustic methodology, the acoustic signature generated by the airfoil for the range of velocities (0.85 ≤ U / U c ≤ 1 near the critical flutter velocity is quantified over a range of acoustic receivers in the surrounding of the airfoil. Sound pressure levels (SPLs) are determined, and directionalities have been studied. It is revealed that the distribution of sound pressure level at the exciting frequency is affected by the gust profile. Scales of these sound pressure levels, however, relied on the Reynolds number and the dynamics of the system.
在二维数值环境中研究了自由响应对称翼型在阵风作用下的声学响应。在入口速度上叠加阵风模型，直至达到临界颤振速度。采用二阶瞬态方程、k−ω湍流模型和动态网格划分技术。采用Ffowcs Williams和hawkins (FW-H)声学方法，在临界颤振速度(0.85≤U / U c≤1)附近的速度范围内，翼型产生的声学特征在翼型周围的一系列声学接收器上进行了量化。确定了声压级(SPLs)，并研究了方向性。结果表明，在激励频率下声压级的分布受阵风廓形的影响。然而，这些声压级的尺度依赖于系统的雷诺数和动力学。

: The steam–water direct contact condensation (DCC) process is commonly observed in various industries due to its fast heat and mass exchange characteristics. This study investigates steam plume characteristics by experimentally condensing the steam jet issuing from a swirled flow spray nozzle into stagnant subcooled water. On the basis of high-speed imaging, the effects of subcooled water temperatures on the cavity shape, its length, and maximum expansion ratio were explored. The existence of three distinct cavity shapes (ellipsoidal, double expansion–contraction and divergent) were identified. The dimensionless steam cavity penetration length and maximum expansion ratio were found to be in the range of 6.28–11.5 and 1.71–3.06, respectively. The results indicate that with the rise in water temperature, plume length and maximum expansion ratio increase.
