Slow wave structure
WebbThe existing measurements of laminar-to-turbulent transition over circular cones in conventional (i.e., “noisy”) hypersonic wind tunnels have established that the transition location moves downstream when the nose radius is increased from zero. However, this initially downstream movement slows down and ultimately reverses beyond a critical … Webb669 Likes, 30 Comments - 홃홤홨홖홞 홈홤홟홖홙홙홞홙홞 (@hosaimojo) on Instagram: "The degree of our disappointments is in direct proportion to the ...
