9727087 Sarma Description: This award is for a joint project in mechanical engineering entitled "US-India Cooperative Research: Two Phase Flow Instabilities in Boiling & Condensing Flow Systems". The co-investigators are Sadik Kakac of the University of Miami and P.K. Sarma of Andhra University in Visakhaputnam. The investigations on two-phase flow instabilities and heat transfer in horizontal in-tube boiling and condensing systems are experimental and theoretical. The main objectives of the research are to study the fundamental mechanisms of various boiling and condensing two- phase flow instabilities, the parametric effects on these instabilities, the interaction between heat transfer and these instabilities, and to model these complicated phenomena mathematically. By combining their expertise, the investigators expect to be able to reveal the similar fundamental physical mechanism of both boiling and condensing flows dynamics and heat transfer, and to further clarify the differences between the two physical phenomena. Scope: This joint project resulted from an NSF supported workshop held at Andhra University in 1995. The research is complementary and mutually beneficial. The US PI has extensive research experience in the study of boiling flow instabilities and oscillations; while the Indian PI has extensive experience in the study of condensing heat transfer and dynamics. Accordingly, experiments in boiling two-phase flow instabilities will be conducted at Miami, while the two-phase flow condensation instabilities and heat transfer experiments will be done at Andhra. Research teams at both universities will participate in each other's experimental investigations, and in the theoretical model development. As a new collaboration and for its involvement of students in the research, this project supports INT objectives. ***

描述：该奖项授予一个机械工程领域的联合项目，名为“美印合作研究：沸腾和冷凝流动系统中的两相流动不稳定性”。共同研究人员是迈阿密大学的萨迪克·卡卡克和维萨卡普特南安得拉邦大学的P.K.萨尔马。对卧式管内沸腾冷凝系统的两相流动不稳定性和传热进行了实验和理论研究。研究的主要目的是研究各种沸腾和冷凝两相流不稳定性的基本机理，参数对这些不稳定性的影响，传热与这些不稳定性之间的相互作用，并建立这些复杂现象的数学模型。通过结合他们的专业知识，研究人员希望能够揭示沸腾和冷凝流动动力学和传热的相似基本物理机制，并进一步澄清两种物理现象之间的差异。范围：这个联合项目源于1995年在安得拉邦大学举行的一个由国家科学基金会支持的研讨会。研究是互补互利的。美国PI在沸流不稳定性和振荡研究方面有丰富的研究经验；而印度PI在冷凝传热和动力学研究方面具有丰富的经验。因此，沸腾两相流不稳定性实验将在迈阿密进行，而两相流冷凝不稳定性和传热实验将在安得拉邦进行。两所大学的研究团队将参与彼此的实验研究，并参与理论模型的开发。作为一个新的合作和它的学生参与研究，该项目支持INT的目标。＊＊＊
