Slices through the z  =  0 plane of (from left to right) cooling rate, density, tangential velocity, v _ϕ , and contribution to the hot gas from the four passive scalars without (upper) and with (lower) thermal conduction. Contribution to hot gas is calculated from the four passive scalars weighted by the mass fraction. The shock–cloud interaction is well-resolved with a resolution of Δx  =  1/64 pc. Cooling is most efficient in the shell surrounding the cold clouds. Dense, cool shells form around the cold clouds. The remnant is altered with a considerable tangential velocity, v _ϕ . Thermal conduction smooths the interior of the hot gas considerably and slightly increases the efficiency of cooling in the hot gas regions.
