HEAT DISTRIBUTION STUDY ON TURBOCHARGER TURBINE’S VOLUTE
Keywords:
Holset turbochargers, heat transfer coefficients, turbine, efficiencyAbstract
The aimed of this project is to evaluate turbine’s performance based on its actual condition. Holset H3B nozzles turbine geometry was used as simulation model. Turbine’s actual working condition was simulated by using finite volume discretiztion method. Initial analysis was done by one-dimensional and two-dimensional analysis. Further investigation was done in three-dimensional with heat loss via turbine volute by the mode of convection. Parameters studied are corrected mass flow, turbine’s efficiency at different heat cases, temperature distribution along turbine’s volute and difference in temperature between inner and outer wall temperature. Temperature difference within turbine’s volute is the major factor that deteriorates turbine’s efficiency. Since turbine wall is thin, small temperature difference will result to high heat loss.References
