We investigate the velocity distribution function of the fluid flow through a model of random porous media. We examine how the form of the distribution changes with porosity. We find a crossover porosity at which the scaling character of the distribution changes and discuss our findings in the context of a nearly exponential velocity distribution function measured recently experimentally [Datta, S.S. et al. (2013) Phys. Rev. Lett. 111: 064501].
