BOILING HEAT TRANSFER WITH CONTROLLED ARRAYS OF NUCLEATION SITES ON SILICON SURFACES

该项目基于以前的项目GR/M89034以及由此产生的仍在出版出版物的国际合作。国际参与者以最低的成本提供复杂系统非线性动力学方面的基本数值模拟和专业知识。该项目利用了已经在爱丁堡得到验证的创新设备的微制造。爱丁堡最先进的设备将以非常低的成本提供进一步的微制造。申请者相信，该项目将对了解成核点之间的相互作用做出重大贡献，从而对成核沸腾的模型做出重大贡献。该项目的风险部分是试图对大量成核点进行局部控制。就提议人所知，这是以前从未尝试过的。通过对相互作用的良好物理理解，进展可以降低风险，但成功还取决于一个极其复杂的系统的非线性动力学。如果成功，这种方法将提供一种方法，在温度变化很小的情况下，消除大的但空间可变的热通量。它将适用于高额定电子器件和极放热反应堆的热管理。

This project is based on a previous project GR/M89034 and the resulting international collaboration that is still producing publications. The international participants provide at minimal cost the essential numerical simulation and expertise on nonlinear dynamics of complex systems. The project exploits microfabrication of innovative devices that have already been proven at Edinburgh. Further microfabrication in state of the art facilities at Edinburgh will be provided at very low cost.The applicants are confident that the project will make a significant contribution to the understanding of interactions between nucleation sites and therefore to the modelling of nucleate boiling. The risky part of the project is the attempt to implement localised control of a large array of nucleation sites. So far as the proposers are aware, this has never been attempted before. The risk is reduced by the progression through good physical understanding of interactions but success also depends on the nonlinear dynamics of an extremely complex system. If successful, this approach will provide a means of removing large but spatially variable heat fluxes with little variation in temperature. It will be applicable to the thermal management of highly-rated electronic devices and extremely exothermic reactors.
