The Use of Arrays of Sensors and Actuators to Control Convective Flows

建议编号：CTS 0212998首席研究员：哈伊姆·鲍尔研究所：宾夕法尼亚大学建议标题：使用传感器和执行器阵列来控制对流PI和他的学生将对热致对流的主动控制进行理论和实验研究。由于这种流动是多自由度的非线性流动，有效的控制是相当困难的。这项研究将扩展之前的工作，以开发所有传感器可以同时与所有执行器交互的方法。将进行数值模拟以研究受控系统的动力学，并将在具有不同纵横比的直立圆柱体中进行实验，使用具有较大普朗特数范围的不同液体，同时使用微制造传感器和执行器阵列。这是一项基础性研究，有可能使控制策略能够改变重要工业过程中的传输现象。这项研究还应有助于将主动控制策略与热传输结合到新的教育材料中。

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.
