Abstract
This paper reviews some processing methods in knowledge engineering and presents a private view about the applicability of knowledge engineering to fluid mechanics. Empirical problems which are desired to be solved by using knowledge engineering are shown and relating studies are refered. Some application systems which are developed by the authors are introduced as concrete examples. Then knowledge engineering ways of thinking, which are expexted to be fruitul, are suggested and some guiding recommendations to pursue studies in this field are made.
