摘要CTS-9523579提出了一项概念验证性研究,用于预测运动流体中的空化和放气。以前使用的基于压力的门槛准则被考虑流动流体中的主应力的门槛准则所取代。将进行实验和直接模拟,以验证所提出的判据在相对简单的装置中的适用性。文献中的相关信息将从这一标准的角度进行审查。如果成功,新标准将从根本上改变我们对流动流体中空化和排气的理解,以及工业中透平机械、液压回路和各种流体流动设施的设计方法。***
英文摘要
ABSTRACT CTS-9523579 A proof-of-concept study is proposed for a new approach to predict cavitation and outgassing in a moving fluid. The previously used threshold criterion based on pressure is replaced by one considering the principal stresses in a flowing fluid. Experiments and direct simulations will be conducted to verify the applicability of the proposed criterion in relatively simple devices. The pertinent information from literature will be reviewed from the perspective of this criterion. If successful, the new criterion will fundamentally change our understanding of cavitation and outgassing in flowing fluid, as well as the design methods of turbomachinery, hydraulic circuits, and various fluid flow facilities in industry. ***
