Abstract This paper continues a physical modelling of a transpiration flow, presented in [P.P. Doerffer, R. Bohning, Aerosp. Sci. Technol. 4 (2000) 525–534], by developing a system of gasdynamic equations for the viscous flow in tubes of a perforated plate. Asymptotic expansions give interesting analytical expressions for the pressure loss in the tubes as a function of Mach number in a perforation hole.
