The computational calculations employing the “x-t” model of a pulsating flow in the pipe and their experimental verification were described. The model, previously used for calculations of pressure signal variations in pneumatic transmission pipes, was adapted to the admission system of the turbocharger turbine. Appropriate boundary conditions were applied, using the experimental data provided by the measurements of unsteady flow parameters. The calculation results were compared to the experimental data showing a good agreement.
