摘要：
An original physical model to calculate the fluid dynamics and energy conversion in twin-entry turbocharger turbines for internal combustion engines is presented. The model is to be used as the boundary condition for one-dimensional wave action techniques and is also capable of considering variable gas properties and composition. The model is based on a simple variable-area approach; however, it is capable of adequately modelling complex flows that occur in multi-cylinder turbocharged engines. This is confirmed through the good agreement between calculated and measured turbine and engine parameters.
