UUM 621E - Advanced Problems in Compressible Flow

Course Objectives

Today, in aerospace engineering subjects, compressible flows have an important place in aerodynamics, since high speed is aimed at external flows and high pressure is aimed at internal flows. Within the scope of this course, it is aimed to summarize the issues related to compressible flow seen at undergraduate level and to examine advanced topics. The course is mainly designed for upper level graduate students. Coding and differential equations knowledge is essential.
