一般注記Propagation of astrophysical jets was investigated numerically by using the Osher method which has a second-order of accuracy in space and time. The characteristic structures of them, i.e. a beam, a lobe, a working surface and a cocoon, were successfully simulated. It was found that those structures were very sensitive to the density ratio (gas density of the jet at the effective nozzle-exit divided by that of the ambient). In the present calculations, the ambient gas condition first introduced by the present authors was applied on all the numerical boundaries. The numerical results have clearly shown that the ambient gas condition is better than the pressure condition adopted, for example, by Norman et al. The ambient gas condition can be widely applied to other problems with numerical boundaries.
