We present results of several simulations performed for a better understanding of the propagation and early phases of interaction of two SNRs embedded in a homogeneous interstellar environment. In particular we have simulated the hydrodynamic evolution and collision of twin SNRs during their self-similar stage using a two-dimensional Lagrangian hydrocode. We also present the results of a simulation of a target that reproduces the same phenomenon through laser ablation of two plastic plugs at laboratory scale. Our results indicate that both large-scale and small-scale simulations display several common features that can be used to design an experiment aimed to validate the hydrodynamical codes. Of particular interest are the structures found around the juncture of the two colliding shells produced by the interaction of the remnants.
