Time evolution of the cloud mass ($M(\rho >\frac{1}{3}{\rho }_{cloud})$; top column) and the mass of intermediate temperature gas (Eq. (56); bottom column). Once can see that it takes about the same time for the cloud mass to be lost in all the different modules, though with a slight faster decrease in the ISPH modules, with the fastest decrease being with the O_I,64 kernel + ISPH. However, the amount of mixing in intermediate temperature gas differs quite a bit, where the optimized kernels increases the amount of mixing in both the ISPH and GDSPH models. The mixing results are reminiscent of the KH mode growth results shown in Fig. 12.
