| Popis: | General correlations were developed in this work for predicting the initial collection efficiency and the filter coefficient ratio under the unfavorable surface condition when electrostatic repulsive force prevents colloidal particles from reaching the filter grain surfaces. Simulation was done by using the Brownian dynamics method and experimental data was used for verifying the general correlations developed. It was found that the theoretical and experimental results fit the predicted filter coefficient ratio best by using algebraic averaged correlations. |
