| Research Abstract |
The purpose of this co-operative research is to make researches, varidations and developments of the turbulence models, in co-operation of the specialists, users and young researchers of the turbulence model in our country, in order to improve this field remarkably. To this end, the following research meetings have been held.

These results were also reported in the Annual Symposia on Computational Fluid Dynamics, the Seiken NST Symposia and so on. A short course "Prectical Applications of Turbulent Flow Analyses" was held in the Pacifico Yokohama during January 22-24, 1992. The participants are about 200 and the course was a great success. The memoir of this co-operative research consists of 17 lectures of this short course and 10 supplement manuscripts. Less
