Abstract
The physical quantities found in transport phenomena, as well as the different physical mechanisms that involve these phenomena, have several applications discussed in several aspects, mainly in the areas of science and engineering. One of these applications is the analysis related to the rate of deposition of particles in a substrate and, in this view, several processes are listed, such as the deposition of particulate matter (PM). In this context, this work seeks to understand and interpret how the phenomenon of PM deposition behaves using a particular case and whose uniqueness promotes the interpretation of the phenomenon of PM deposition in a more limited scenario and that simplifies external variants. In the approach adopted here, particle deposition is analyzed in detail in a symmetrical circular tube with a fully developed laminar flow, which, in this way, can be interpreted as a PM tubular filter. The adoption of this approach will allow an analysis of the deposition analytically, based on the Graetz problem. Preliminary results show that this approach to be in line with the physics of the proposed problem and it has the potential to foster discussions about applications for the Gratez problem.
