Abstract
In this paper the physical and the mathematical model of a three-temperature plasma is presented. The numerical algorithm used to solve this problem is also described. A special technique has been used to treat very rapid electron-ion and electron-radiation energy equipartition rates in inertial fusion plasmas. This model has been incorporated in the one-dimensional computer code medusa-ka. (N. A. Tahir and K. A. Long, ‘‘medusa-ka: A one-dimensional computer code for inertial fusion target design,’’ Kernforschungszentrum Karlsruhe Report, KfK-3454, 1983). Application of this model to study the problem of ignition and burn propagation in reactor-size inertial fusion targets is also briefly discussed.
