Abstract

ABSTRACT
Numerical Model and analysis on performance of a straight-through swirl tube cyclone
Soroush Saberi
A numerical simulation for the rotational flow inside a special configuration of inertial gas-solid separators is performed. The inertial gas-solid separator of the present work can be fit in category of straight-through swirl tube cyclones. Using the results of parametric studies a modified geometry configuration for the inertial gas-solid separator is achieved which shows considerable performance improvement in comparison with the original model. In this approach, the CAD model for the original geometry of the dust separator was generated and the turbulent flow field was solved using time-independent solver and Reynolds stress turbulence model. The solution approach demonstrates consistency with the a
vailable experimental data proving the accuracy of the solution method. The highly rotational flow pattern and its features are described by analyzing the different flow variables. The main contributors of the pressure loss production in the flow field are identified and the most effective geometry parameters are recognized in order to perform the parametric analysis. The modifications are implemented on the original geometry and flow simulation is performed for each new configuration with the same solution method as used for the original model. The flow field changes are evaluated by comparing the contours of flow variables and the generated pressure loss for each case are compared with original configuration. Considering the results of parametric studies, a final model was made and solved numerically. The results show that the final modifications will result in considerable improvements in the amount of pressure loss while preserves the same dust collection efficiency.
