Turbo muffler is designed this way – specifically to reduce restriction and allow exhaust gases to flow out easily. Turbo muffler is wrapped around fiberglass packing that’s great for absorbing sound waves.
Webb8 okt. 2007 · In this article the structure of fully developed turbulent pipe and channel flow has been studied using custom-made arrays of hot-wire probes. Results reveal long meandering structures of length up to 25 pipe radii or channel half-heights.
