T1 - Accurate experimental speed of sound data of natural gas and hydrogen-enriched natural gas N2 - The work presents speed of sound data of an 11-component synthetic natural gas as well as of a hydrogen-enriched natural gas measured at temperatures between 260 and 350 K and pressures up to 13 MPa. The results are compared with the corresponding values from two equation-of-state models, namely AGA8-DC92 and GERG-2008.
