Numerical simulations for radiation hydrodynamics. II: Transport limit
[For part I, see the authors, ibid. 142, No. 1, 182-207, Art. No. CP985940 (1998; Zbl 0933.76057).] From the summary: A finite difference scheme is proposed for two-dimensional radiation hydrodynamical equations in the transport limit. The scheme is of Godunov-type, in which the set of time-averaged flux needed in the scheme is calculated through Riemann problems. In the scheme, flow signals are explicitly treated, while radiation signals are treated implicitly. Flow fields and radiation fields are updated simultaneously. An iterative approach is proposed to solve the set of nonlinear algebraic equations arising from the implicitness of the scheme. The sweeping method used in the scheme significantly reduces the number of iterations or computer CPU time.
