Recent advancement in fabrication of ultra-clean samples (in graphene and in semiconductor heterojunctions [1]) has led to the realisation of a new regime of electron transport previously unexplored, i.e, the hydrodynamic regime. In this work, the implications of hydrodynamic transport through interfaces with varying density profiles in 2DEGs are explored, as well as possible experimental realisation is discussed.
