* 충격파 : (normal shock wave), (oblique shock wave), (detonation wave)
* 등엔트로피 유동 : 수축(isentropic compression) 및 등엔트로피 팽창(isentropic expansion), (Prandtl-Meyer expansion flow)

* externe Strömungen, z. B. über Flugzeugen oder Wiedereintrittskörpern (Space Shuttle, Landekapseln von Raumschiffen), als auch
* interne Strömungen durch Düsen und Diffusorenerne Strömungen durch Düsen und Diffusoren
, La Gasdinamica è una branca della fluidodi … La Gasdinamica è una branca della fluidodinamica che si occupa dello studio dei moti gassosi e dei suoi effetti con i sistemi fisici, basandosi sui principi della meccanica dei fluidi e della termodinamica.Tale disciplina sorge dalla necessità dello studio dei flussi gassosi, spesso all'interno o nelle vicinanze di corpi, specialmente a velocità comparabili con la velocità del suono o oltre, ed a volte con significative modifiche di gas ed oggetti. Alcuni esempi di tali studi includono (ma non si limitano) fenomeni di in ugelli di scarico e valvole, onde d'urto di aereo a reazione, , rientro atmosferico, flusso di Rayleigh in motori a reazione. A livello molecolare, la gasdinamica è lo studio della teoria cinetica dei gas, che spesso conduce a studi di diffusione molecolare, meccanica statistica, termodinamica chimica e termodinamica del non equilibrio. La gasdinamica è sinonimo di aerodinamica quando il gas considerato è l'aria e l'oggetto di studio è il volo. La gasdinamica è molto utilizzata in fase di progettazione di veicoli aerei e veicoli spaziali e dei rispettivi .erei e veicoli spaziali e dei rispettivi .
, Gasdynamik är den del av strömningsmekanik … Gasdynamik är den del av strömningsmekaniken som handlar om gasers rörelse. Gasdynamik som ämne är fokuserat på studier av kompressibel strömning. Machtalet spelar en stor roll i sådan strömning. Skillnaden mellan ämnesområdena gasdynamik och aerodynamik är att aerodynamiken även omfattar studier av luftens påverkan på föremål som rör sig i den. Gasdynamik kan således sägas vara en grund för aerodynamiken, som även omfattar ett bredare ämnesområde.som även omfattar ett bredare ämnesområde.
, Gas kinetics is a science in the branch of … Gas kinetics is a science in the branch of fluid dynamics, concerned with the study of motion of gases and its effects on physical systems. Based on the principles of fluid mechanics and thermodynamics, gas dynamics arises from the studies of gas flows in transonic and supersonic flights. To distinguish itself from other sciences in fluid dynamics, the studies in gas dynamics are often defined with gases flowing around or within physical objects at speeds comparable to or exceeding the speed of sound and causing a significant change in temperature and pressure. Some examples of these studies include but are not limited to: choked flows in nozzles and valves, shock waves around jets, aerodynamic heating on atmospheric reentry vehicles and flows of gas fuel within a jet engine. At the molecular level, gas dynamics is a study of the kinetic theory of gases, often leading to the study of gas diffusion, statistical mechanics, chemical thermodynamics and non-equilibrium thermodynamics. Gas dynamics is synonymous with aerodynamics when the gas field is air and the subject of study is flight. It is highly relevant in the design of aircraft and spacecraft and their respective propulsion systems.t and their respective propulsion systems.
