Abstract
An alternative method for the buoyant plume rise computation is proposed. It is based on the same idea described in a recent paper related with chemical reactions in Lagrangian particle models (Alessandrini S and Ferrero E, Phys A 388:1375–1387, 2009) for simulating the ozone background concentration. A fictitious scalar transported by the particles, the temperature difference between the plume portions and the environment air temperature, is introduced. As a consequence no more particles than those inside the plume have to be released to simulate the entrainment of the background air temperature. In this way the entrainment is properly simulated and the plume rise is calculated from the local property of the flow.
