  "abstract": "Using kinetic theory of gases, we derive the diffusive compressible Euler (dcE) model for ideal gases. The derivation covers all steps from the particle description of a gas, to macroscopic averages, to a discrete system of conservative balance equations in finite volumes, to the system of partial dif- ferential equations. Along the way, we discuss the modelling assumptions, and derive approximations of the diffusion coefficient. In the next part, we discuss the modifications needed to model real gases. In particular, we propose a tentative model for intermolecular friction forces.",
