Boundary layer closure and heat transfer in constant base pressure and simple wave guns
Abstract
Solutions of the two-dimensional, unsteady integral momentum equation are obtained via the method of characteristics for two limiting modes of light gas launcher operation, the 'constant base pressure gun' and the 'simple wave gun'. Example predictions of boundary layer thickness and heat transfer are presented for a particular 1 in. hydrogen gun operated in each of these modes. Results for the constant base pressure gun are also presented in an approximate, more general form.
