Abstract
The pulsating flow in a duct with a junction was studied numerically using a Random-Choice Method and the experiments were carried out to check if this numerical simulation is valid or not. As a result, good agreement was found between the experiment and numerical calculation. Concerning the location of the shock wave the agreement was excellent. The Random-Choice Method may be applied to real reciprocating engines by coupling it to a multi-dimensional in-cylinder simulation.
