| Abstract: | The aerodynamic resistance and aerosol-catching efficiency of fine, high-efficiency, and ultrahigh-efficiency multilayer cermet filters were measured at a gas velocity of 1–200 cm/s, 300°C, and gas pressures up to 50 atm. At small Reynolds numbers, the flow resistance of flat and cylindrical filter elements depends linearly on the gas velocity and is almost independent of the gas pressure. The effect of temperature on the flow resistance is explained by the temperature dependence of gas viscosity. The collection efficiency for particles larger than 0.2  m in diameter grows with increasing particle size and gas velocity. |
