Abstract
This paper presents a CFD model of reverse-flow extended-tube muffler which is analyzed by a set of experimental tests, in order to acquire the relations between the structure and its corresponding pressure loss; a lot of research have been done through the numeric simulation. For the specific model, the distance from inlet pipe’s rear to the end cap has a large impact on the pressure loss, furthermore, a critical value about the distance has been found: If the distance is less than the critical value, the pressure loss will sharply rise; If the distance is larger than it, the pressure loss will change little. In the end, to calculate the critical value about the distance, evaluation formulary is displayed, which possesses great importance to the design of muffler and its pressure loss prediction.
