Abstract

The development of micro/nano fabrication technology has enabled the size of many engineering devices to shrink significantly over the past two decades. Among these are many micro thermal systems where fluid flow and heat transfer play an important role. These include micro heat exchangers, micro heat pipes, micro total analysis systems, micro pumps, ink jet heads, and so on.

This talk is intended to present a method for modeling transport phenomena in microstructures. It is followed by three types of micro-sensors developed for experimental investigation of fluid flow and heat transfer in microstructures. The modeling technique based on the averaging method is applied to thermal design and optimization of a microstructure. The micro-sensors can be used to measure the temperature distribution at the surface of a microstructure and the mass flow rate passing through it. Some of the latest micro thermal systems will be discussed with examples of application.
