Heat transfer in the lithiumcooled blanket of a pulsed fusion reactor
Abstract
The transient temperature distribution in the lithiumcooled blanket of a pulsed fusion reactor has been calculated using a finiteelement heatconduction computer program. An auxiliary program was used to predict the coolant transient velocity in a network of parallel and series flow passages with constant driving pressure and varying magnetic field. The coolant velocity was calculated by a RungeKutta numerical integration of the conservation equations. The lithium coolant was part of the finiteelement heatconduction mesh with the velocity terms included in the total matrix. The matrix was solved implicitly at each time step for the nodal point temperatures. Slug flow was assumed in the coolant passages and the Boussinesq analogy was used to calculate turbulent heat transfer when the magnetic field was not present.
