Modelling and experimental investigation of transientgas flow through triple junction
Modelling and experimental investigation of transient-gas flow through triple junction Experimental verification of a model accounting for flow in a triple junction of a pipeline is conducted. The model is based upon assumption that pressures at the ducts' endings are equal. Single-cycle test setup equipped with different pipelines is used in experiments. Motion of finite amplitude waves is simulated numerically based on the system of conservation laws of gas dynamics in one dimensional formulation. In all cases comparisons between measured and computed pressure curves taken at certain location has demonstrated valuable variances due to the assumption used by the model of triple junction.
