Thermal-hydraulic characterization of high heat flux components for fusion reactors
Activity responsible: Dr. Andrea
The experimental program carried out on the STAF loop is devoted to study the influence of the geometrical and thermal-hydraulic parameter on the critical heat flux in subcooled flow boiling, in the case of high heat flux and high velocity and subcooling of the refrigerant (water).
The STAF loop can be equipped with a visualized test section to obtain images of the phenomenon.
The test loop (STAF) is made of stainless steel, and the fluid refrigerant is deionized and demineralized water.
The main characteristic of the loop are:
Vertical cylindrical pipe (AISI 316), diameter ranging from 0.25 to 8.0 mm and heated length ranging from 10 mm to 150 mm, used for tests of critical heat flux in tube.
Vertical annular channel with square section (7x7 mm) with two faces made in plexiglass with cylindrical heated rod at the centre, heated length 100 mm (used for visualized critical heat flux test)
