Abstract : The velocity, temperature, and magnetic-field distributions in a compressible and viscous fluid, both thermally and electrically conducting, induced by the impulsive motion of an infinite flat plate in its own plane are obtained by applying the inner-outer expansion technique of Kaplun, Lagerstrom and Cole (P. A. Lagerstrom and J. D. Cole, J. Rat. Mech. Anal. 4, 817-882 (1955); S. Kaplun and P. A. Lagerstrom, J. Math. Mech. 6, 585-593 (1957).) The problem is first discussed in general terms. Details are then taken up for the limiting case of infinite electric conductivity with a discussion of the connection between this and the case of large but finite conductivity via a magnetic boundary layer. The applicability is shown of the expansion technique to problems of this kind and the interaction is demonstrated between the inner and the outer flow regions. No numerical calculations are undertaken. (Author)
