Air-Sea Intevaotions ; Program at IMST 



Fig. 18. Air-Sea Interactions Laboratory Floor Plan 



The preliminary design of the facility has been determined by 

 I.M.S.T. , and its detail drawings set up with the aid of architect 

 and engineering offices. The construction works have been planned 

 in three stages: a) Erection of buildings , concrete structural parts 

 of the tunnel, electric equipments, temperature and humidity con- 

 trol systems; b) Fitting up of the main elements of air and water 

 circuits, including static parts (tunnel walls etc.) as well as pump 

 and fan; c) Completion and equipment of the facility, placing control 

 apparatus and such parts as wave-maker and boundary layer control 

 devices in position. 



Works have been started in January 1969, and step a) is 

 fully completed from several months (see Fig. 19). Step b) is now 

 nearly achieved, and the first run of the wind-water tunnel is planned 

 for the end of the present year. Our program forecasts about one 

 more year for the execution of step c) , and the beginning of strictly 

 scientific experiments by the end of 1971. These experiments will 

 concern: first the dynamic exchange process alone; then, the heat 

 and mass transfer processes; and later on the effects of stratifica- 

 tion upon these three mechanisms. The execution of this program 

 will clearly take several years. 



VI. RESEARCHES RELATED TO INSTRUMENTATION PROBLEMS 



Some of the anticipated experiments obviously necessitate, 

 either the development of new measuring instruments and methods, 

 or the adaptation of existing ones. Corresponding researches have 

 been undertaken since the early stages of our program. 



Note added in proof: this has been achieved by November 1970.
