Electrical effect of soot depositions in a co-axial wire pipe flow

An investigation was performed to study the electrical effects on the soot deposition in a co-axial wire cylinder with cooled walls. Experiments were performed for applied voltages from 0 to −5kV or +5kV and a diesel exhaust mass flow rate of 20kg/h or Reynolds number of approximately 9000. The outer wall was cooled using water with a temperature of approximately 40°C, and the experiments were performed for exposure times of 2h. The soot …
