DEVELOPMENT OF MICRO HEAT TRANSFER IN MANUFACTURING AND PROCESSING OF NEW MATERIALS

本项目旨在从微观角度研究新材料制造和加工过程中的传热过程。研究结果将大大提高产品的质量和精度。当需要对现象有更全面的理解时，基于连续介质前提的经典传热理论显示出令人遗憾的弱点。在与新材料的制造和加工有关的技术领域，需求尤其强劲。为了更全面地理解热传递的基本原理，必须理解微尺度现象，其极端是原子和分子的行为。因此，我们打算在传热中建立一个新的范例。为此目的，我们组织了五个小组来研究具体的课题。它们是：A01：凝结的分子热工程研究；A02：凝固的微观/宏观组合建模；A03：凝固的高精度测量和主动控制；A04：非晶材料制造的超快速冷却技术的开发；A05：超高精密加工中熔化、蒸发和升华过程的研究。为有效执行这一项目，组织了一个指导委员会。它开始于1993年4月，结束于1997年3月，但最后一年用来汇集过去三年取得的所有成果。今年主要完成的项目如下：指导委员会会议（两次）：1996年5月16日和1962年12月3日。在文武院为采访做准备的会议：1963年10月15日。在文武院的采访：1964年10月17日。1996年12月1日至4日在“材料加工和其他应用中的分子和微尺度热传递”国际研讨会上举行的最终报告介绍会议。(5)最终报告的出版：将于1997年4月出版

This project aims at investigation of heat transfer processes in manufacturing and processing of new materials from a microscopic point of view. Quality and precision of products would be improved greatly as the result of this investigation. Classical heat transfer based on continuum premises reveals a reprehensive weakness when a more complete understanding of phenomena is demanded. The demand is especially strong in the area of technology related to manufacturing and processing of new materials. For more complete understainding of the fundamentals of heat transfer, microscale phenomena, the extreme end of which is the behavior of atoms and molecules, shoud be understood. Thus, we have intended to establish a new paradigm in heat transfer.To this end we organized five subgroups pursuing specific subjects. They are : A01 : Molecular thermal engineering research on condensation, A02 : Micro/Macro combined modelling of solidification, A03 : High-precision measurement and active control of solidification, A04 : Development of ultra-rapid cooling technique for manufacturing of amorphous materials, A05 : Study on melting, evaporation and sublimation processes in ultra-high precision processing.A steering committee was organized for an effective implementation of this project. It started in April 1993 and finished in March 1997, but this last year was spent to get together all the results obtained during the past three years. The main items done in this year are as follows :1. Steering committee meeting (twice) : May 16,1996 and December 3,19962. Meeting in preparation for the interview at the Monbusho : October 15,19963. Interview at the Monbusho : October 17,19964. Final report presentation meeting at the International Symposium on Molecular and Micro-scale Heat Transfer in Materials Processing and Other Applications : December 1-4,1996(5) Publication of the Final Report : To be published in April 1997
