Název v původním jazyce
Prediction of gas leakage through the turbocharger sealing system
Popis výsledku v původním jazyce
The phenomena called compressor fouling is partly influenced by the gas leakage flow from the seal system of the turbocharger rotor. The prediction of gas flow through the sealing system depends not only on many design parameters but also on the operating conditions of the turbocharger. The paper presents experimentally validated computational model to quantify the mass flow of gases through the sealing system as a function of operating conditions. The computational model is applied to a truck engine turbocharger and the results are verified experimentally. The results show that the magnitude of gas blow-by is not only influenced by the geometrical parameters of the lubrication system, but is controlled by the thermo-mechanical loading of the turbocharger with a non-negligible influence of the radial dynamics of the rotor.
