P. Ciecielag et al., High-resolution simulations and visualization of protoplanetary disks: structure of the flow in the vicinity of a massive planet, ASTRON NACH, 321(3), 2000, pp. 171-174
A problem of mass flow in the immediate vicinity of a planet embedded in a
protoplanetary disk is studied numerically in two dimensions. Large differe
nces in temporal and spatial scales involved suggest that a specialized dis
cretization method for solution of hydrodynamical equations may offer great
savings in computational resources, and can make extensive parameter studi
es feasible. Preliminary results obtained with help of Adaptive Mesh Refine
ment technique and high order explicit Eulerian solver are presented. This
combination of numerical techniques appears to be an excellent tool which a
llows for direct; simulations of mass flow in vicinity of the accretor at m
oderate computational cost. The present communication is focused on the str
ucture of the outer part of the circumplanetary disk. We employ the multifl
uid option to the hydrodynamical solver to prove that the circumplanetary d
isk is composed of the gas transfered into it from the edges of the gap.
