In this paper,a compensated compactness framework is established for sonicsubsonic approximate solutions to the n-dimensional (n ≥ 2) Euler equations for steady irrotational flow that may contain stagnation points.This compactness framework holds provided that the approximate solutions are uniformly bounded and satisfy Hlloc-1 (Ω) compactness conditions.As illustration,we show the existence of sonic-subsonic weak solution to n-dimensional (n ≥ 2) Euler equations for steady irrotational flow past obstacles or through an infinitely long nozzle.This is the first result concerning the sonic-subsonic limit for n-dimension (n ≥ 3).
