Preface: Recent Advances in the Analysis and Simulation of Compressible Flow Problems: The 75th Anniversary of the Landmark Report by Lagerstrom, Cole, and Trilling (1949)#

This special issue of Studies in Applied Mathematics commemorates the 75th anniversary of the publication of the highly influential 1949 “GALCIT” report by Lagerstrom, Cole, and Trilling, a work which helped usher in the modern era of compressible flow studies. Herein, a collection of papers highlighting recent advances in the treatment of topics/problems relating to both lossless and dissipative compressible flow phenomena is presented.
