This works describes the test configuration of gas dynamic energy disjunction device (Leontiev’s tube) working on the natural gas. This device works by means of local disbalance between heat generation and dissipation during the flow of compressible gas. Results of experimental investigation of the specified device and measuring error estimate were presented in this article. Updated method of calculating this class of devices was proposed; it allows one to consider the intensification of heat transfer at the initial section of a supersonic channel along with the influence of the longitudinal pressure gradient and the longitudinal thermal conductivity of this device’s walls. The comparison of the results obtained from numerical experiments with a use of updated method with the results obtained from the same experiments with a use of basic method and experimental data was carried out. It was also shown that results of this research obtained using the updated method describe the growth of natural gas’ enthalpy better than ones obtained with a use of basic method.
