Some Important Problems and Progress in Micro / Nano-scale Thermal Science and Engineering

Abstract

This paper describes the significance, content, progress and corresponding basic theory and experimental research methods of micron/nanometer scale thermal science and engineering, which is one of the latest cutting-edge disciplines, and analyzes the effects of micron nanometer devices on the scale effect series of challenging hot issues, discussed the corresponding emergence of some new phenomena and new concepts, pointed out that the micron/nano thermal science aspects of the recent development of several types of theory and experimental technology success and shortcomings, and summed up a number for the exploration of the new ways and new directions, especially on some typical micron/nano-thermal devices and micro-scale biological heat transfer in some important scientific issues and their engineering applications were introduced.

Design Parameters for Small Engines Based on Market Research

“…Tight tolerances result in difficulty in fabrication and increased cost [11]. However, advances have been made in regards to manufacturing processes for smaller electrical-mechanical devices; these advances have been translated into the development of small engines [12].…”
