Abstract: The Orr-Sommerfeld (OS)problem is analyzed in terms of the relation between complex-valued wavenumber alfa and celerity c. For the long-wave regular branch, Taylor series to c(alfa) is found to be of limited use, as its convergence radius pi is to small. Wave characteristics of the conception region, including besides c(alfa) also the wall shear rate impendance q , are obtained for the maximum spatial growth rate scenarioo by solving the OS problem numerically.
Keywords: inception region; linear stability; waves on falling films
