Primary research of heat flux deposition pattern on the surface of HT-7 movable limiter
چکیده انگلیسی

This paper presents a method of characterizing the heat flux deposition pattern on HT-7 movable limiter, a new component in the spring experimental campaign of year 2006. A new modeling establishment combines with heat transfer simulation with ANSYS code, and a shot of long pulse discharge is chosen with small radius 265 mm of movable limiter, which is 5 mm smaller than that of the main toroidal limiters. Both parallel and perpendicular heat flux are taken into account and different ratios of them are also tested in simulations. The simulation temperature values match well with the results of the IR-camera. Temperature distribution shows that ϕ||/ϕ⊥ = 5 is quite suitable in HT-7 device, and the maximum heat flux is about 10 MW/m2 and average heat flux is about 5 MW/m2 on the movable limiter. This method can be also used in other tokamak devices with limiter configuration and circular cross-section shape.
