摘要: This study examines the evaporation loss of submicron. monodisperse ammonium nitrate particles during filter sampling when the upstream saturation ratio is zero. The proposed model has considered the upstream particle concentration, the porosity of the particle bed, particle diameter, upstream temperature, pressure drop. According to the present results, upstream particle concentration heavily influences the evaporation loss of ammonium nitrate particles. Theoretical results agree reasonably well with the experimental data obtained in the laboratory under well-controlled conditions. Results presented herein confirm that the simplified theory by Zhang and McMurry (1992) provides a reasonable yet somewhat lower collection efficiency of volatile species during filter sampling owing to the assumptions in the downstream saturation ratio and pressure drop.
