The use of putational fluid dynamics (CFD) to predict internal and external flows has risen dramatically in the past decade. In the 1980s the solution of fluid flow problems by means of CFD was the domain of the academic, postdoctoral or postgraduate researcher or the similarity trained specialist with many years of grounding in the area. The widespread availability of engineering workstations together with efficient solution algorithms and sophisticated pre- and post- processing facilities enable the use of mercial CFD codes by graduate engineers for research, development and design tasks in industry. The codes that are now on the market may he extremely powerful, hut their operation still requires a high level of skill and understanding from the operator to obtain meaningful results in plex situations. The long learning curve, previously including apprenticeships of up to four years - more widely known as MPhil and PhD studies - meant that the users of the 1980s were, through their own experiences, very con

《气液两相流动态特性的研究》的主要内容是在对气液两相流动基本理论、基本实验和外该领域研究成果、分析研究的基础上,归纳和总结了作者本人及其所领导的课题组二十余年来在两相流动态特性分析方面的研究成果,对目前正被逐渐接受并应用的各种不同类型的动态研究方法作了较详细的介绍。同时,作为对该方法的最早应用者之一,作者在书中重点介绍了本人对两相流动波动、非线性和混沌特性的研究工作。根据确定性混沌动力学和时间序列分析方法的基本原理和实验建模法的步骤,提出一种新的进行两相流动态分析的方法--混沌时间序列分析方法。书中还介绍了作者开发的用于进行气(汽)液两相流动态特性分析的混沌时间序列分析软件(WLCHAOS),以及上述方法在气液两相流实验系统中进行实际分析的研究结果。
