New Type

In this paper, a new type of vertical scrubber is designed and a computational fluid dynamic analysis of gas flow through the device is presented. The simulation results are obtained by FLUENT 6.3. Through the two-dimension simplification of mist-mat, the resistance characteristic of the wire-mesh is gained. To simulate the gas flow of the scrubber, mist-mat is replaced by porous media. Through the analysis of simulate results, flow characteristic and pressure drop of the scrubber is obtained. Additionally, CFD analysis results show the entrance direction of the gas in vane inlet symmetry plane is benefit to avert severely velocity impulse and scrubber’s pressure drop rises with the growth of the eliminator’s velocity.

Flow Through

This paper aims to study comprehensively the flow characteristics of exhaust gases through different types of muffler (e.g. absorptive, reactive and resonating). Geometric models were designed using PRO-E and analysed using ANSYS FLUENT 14. The contours for the pressure, the velocity and the turbulence were plotted for optimization of the muffler design based on the known thermodynamic parameters. On the basis of the variation in these parameters, various hybrid designs were proposed for a muffler and even for a combination of mufflers.
