How do we calculate the position of a normal shock in a converging-diverging (CD) nozzle? In this video, we will go through the necessary calculations in order to compute the area ratio of the normal shock (and thus its position if you know how the nozzle's area changes with axial position).

#VeritasiumContest The basis of all rocket science is the Laval nozzle, but how does it actually work? Sure the flow accelerates in the converging section, but why does it accelerate again in the diverging section? Shouldn't it slow down there? What does this have to do with the speed of sound? Highly unintuitive, and an extensive Google search is unlikely to help. Fluid dynamics is incapable of providing an intuitive answer because it deals with fluid elements, forgoing individual random thermal motion of particles. By considering individual particles, it takes only 1 minute to understand something few do! This video was inspired by a statistical mechanics course; SM connects thermodynamics and individual particle behavior, which in this case clarifies an otherwise very difficult to understand phenomena. A quantitative thermodynamic explanation to complement this 1 minute qualitative one: grc.nasa.gov/WWW/K-12/airplane/machrole.html. olaf.willocx🤍student.kuleuven.be
Today we're talking about the De Laval nozzle. This nozzle is typically used for rocket engines or high-performance jets.

In this video, I want to try and convince you that supersonic nozzles aren't some magical, counter-intuitive device that can only be explained by mathematics. I've done my best to provide what I think is a good intuitive explanation. It does require a basic knowledge of normal shocks and oblique shocks, but hey, I didn't say it was easy! In any case, I briefly discuss shocks as well. Enjoy! Link to the detailed analysis by Josh the Engineer: 🤍 #supersonic #nozzle #rocket #propulsion #shock #shockwave #machdiamond #chokedflow

This lecture describes the behaviour of CD Nozzle when Back pressure is varied. Nozzle behaves ideal i.e., increase velocity/reduce pressure only if the designed back pressure prevails downstream of the Nozzle, otherwise it will act as a diffuser or Shock occurs inside the Nozzle.

In my converging-diverging (CD) nozzle video (link below), we saw that there were seven different flow conditions in a nozzle. If know what exit-to-reservoir pressure ratio our engine is operating at (see notes below), then we can define what condition our nozzle is operating at based on three pre-computed pressure ratios: 1) Choked Isentropic Subsonic 2) Normal Shock at Nozzle Exit 3) Choked Isentropic Supersonic In this video, we will compute the pressure ratios needed to obtain the three states listed above for a given nozzle area ratio (Ae/At). = NOTES = → In this video, we can say that At = A* for each case because the flow is choked, and we do have sonic flow at the throat. → We generally know the exit-to-reservoir pressure ratio that our engine is operating at. For instance, if we are analyzing the Space Shuttle Main Engine (RS-25) on the launchpad, then we know the exit pressure is approximately 101.325 kPa. We also know from the engine's specifications that the reservoir (or chamber) pressure is approximately 20.64 MPa. Dividing the two appropriately gives the pressure ratio we are looking for. = RELEVANT LINKS= → Blog Post - Converging-Diverging Nozzle Pressure Delineations 🤍 → Solving the Area-Mach Number Relation 🤍 → CD Nozzle MATLAB Code - GitHub 🤍 → Compressible Flow Relations Code - GitHub 🤍 = RELEVANT VIDEOS = → Explained: Converging Diverging Nozzle 🤍 → Area-Mach Number Relation [CPG] 🤍 → Normal Shock Relations 🤍 → Stagnation Relations 🤍 = REFERENCES = ► Modern Compressible Flow, Anderson ► Gas Dynamics, Volume 1, Zucrow and Hoffman ► Elements of Gasdynamics, Liepmann and Roshko
