ABSTRACTProposal Number: CTS 0212998 Principal Investigator: Haim BauInstitution: University of PennsylvaniaProposal Title: The Use of Arrays of Sensors and Actuators to Control Convective FlowsThe PI and his students will undertake a theoretical and experimental study of active control of thermally induced convective flows. Because such flows are nonlinear with many degrees of freedom, effective control is quite difficult. The research will extend previous work to develop means by which all sensors can interact with all the actuators simultaneously. Numerical simulations will be carried out to study the dynamics of the controlled system, and experiments will be conducted in upright circular cylinders with different aspect ratios, using different liquids having a wide range of Prandtl numbers, while employing arrays of micro-fabricated sensors and actuators. This is a fundamental study that has the potential of enabling control strategies for modifying transport phenomena in significant industrial processes. The research should also facilitate the integration of active control strategies with thermal transport into new educational materials.

项目编号：CTS 0212998项目负责人：Haim baum机构：美国宾夕法尼亚大学项目名称：利用传感器阵列和执行器控制对流流动PI及其学生将对热诱导对流流动的主动控制进行理论和实验研究。由于这类流动是非线性的，具有多个自由度，因此有效控制是相当困难的。该研究将扩展先前的工作，以开发所有传感器可以同时与所有执行器交互的方法。将进行数值模拟来研究受控系统的动力学，并在具有不同宽高比的直立圆柱体中进行实验，使用具有广泛普朗特数的不同液体，同时使用微制造传感器和执行器阵列。这是一项基础研究，有可能使控制策略能够改变重要工业过程中的运输现象。该研究还应促进将热传输的主动控制策略整合到新的教育材料中。
