摘要

An approach based on the theory of high-mass transfer rates with a blowing parameter. which is extended from previously published correlations, is developed for evaluating aerosol particle deposition onto a vertical flat plate. The airflow driven by a buoyancy force is considered as a two-dimensional. incompressible and steady-state laminar natural convective flow. The approach can be easily implemented in a hand calculation for making predictions of the particle deposition rates under a room environment. While the predicted results are compared with data from previous works using similarity analysis and through numerical integration. we find that the comparison shows a very good agreement.
