This is a collaborative research project between Prof. N. Asgriz of SUNY Buffalo (USA) and Prof. A. Manchaca-Rocha of UNAM (Mexico) in the area of collisional dynamics of liquid drops. The objectives are to investigate the influence of drop shape and drop internal circulation, and to develop a criterion for the fragmentation of collided drops. This is a combined computational-experimental study, where the U.S. participant will focus on numerical simulations, and the Mexican counterpart will contribute with the experimental investigation. Several simplifying assumption are adopted in the volume tracking simulations, such as neglecting of the interstitial gas because of high inertial effects. Fundamental understanding of complex droplet collisions for a large range of variation of the collision Weber number, as well as obtaining practical fragmentation correlations, are expected. The project has relevance to a variety of technologies and natural processes, including spray technology, fuel combustion, nuclear physics and rain drop dynamics. This project is in response to the NSF-CONACyT initiative announcement.

这是一个合作研究项目，教授N。Asgriz和A. Manchaca-Rocha的UNAM（墨西哥）在液滴碰撞动力学领域。 其目的是调查的影响，滴形状和滴内循环，并制定一个标准碰撞滴的破碎。 这是一项计算与实验相结合的研究，美国参与者将专注于数值模拟，墨西哥同行将参与实验研究。 在体积跟踪模拟中采用了一些简化的假设，如由于高惯性效应而忽略间隙气体。 复杂的液滴碰撞韦伯数的变化范围很大，以及获得实际的碎裂相关性的基本理解，预计。 该项目涉及各种技术和自然过程，包括喷雾技术、燃料燃烧、核物理和雨滴动力学。 该项目是对NSF-CONACyT倡议公告的回应。
