Title: Novel Turbo Compressor System with Liquid Erosion Resistance
Authors: Yudanov, Marina
Abstract: This thesis investigates the prevention of liquid impingement erosion of a DME truck turbo compressor for low-pressure EGR. The work attempts to build a methodology for assessing liquid impingement erosion in this application, and to investigate the possibility of mitigating erosion by including a special nozzle in the intake. This problem is addressed with computational uid dynamics using Star-CCM+, where one-phase simulations are run to correspond to a physical Volvo test case for the new nozzle design. Different erosion models from the literature are formulated and compared to experimental studies in the literature and then applied to this Volvo test case. The overall result is that this new design will decrease the erosive potential of exhaust gas condensate for this application.
