What is another word for normal shock compression?
Pronunciation: [nˈɔːmə͡l ʃˈɒk kəmpɹˈɛʃən] (IPA) 
Normal shock compression occurs when a shock wave compresses a fluid flow from a supersonic speed to a subsonic speed. Some synonyms for normal shock compression include normal shock wave, oblique shock wave, and Mach wave. These terms refer to different types of shock waves that can occur in fluid flow, but they all share the characteristic of compressing the fluid and decreasing its velocity. Normal shock compression is prevalent in many areas of fluid mechanics, ranging from aerospace engineering to gas dynamics. Understanding the properties and effects of normal shock compression is important in the design and analysis of various engineering systems, from aircraft engines to rocket propulsion.
