چکیده انگلیسی


- The capillary constant of methane/hydrogen mixtures has been measured.
- The surface tension of methane/hydrogen mixtures has been calculated.
- The measurements were made by the differential capillary method.
- Equations for the capillary constant and surface tension have been offered.
- Methane/hydrogen mixtures are a promising kind of fuel for transport.

Methane/hydrogen mixtures are a promising kind of fuel for automobile, water and railway transport, supersonic aircraft, and rocket engineering. We have used the differential capillary method to measure the capillary constant a2 and calculate the surface tension σ in the temperature range from 95 to 176 K and the pressure range from that of the saturated vapors of pure methane to 4 MPa. Equations have been derived which describe the temperature, baric and concentration dependences of a2 and σ. The adsorption has been determined. The results of measurements are discussed in the framework of thermodynamic models of the theory of surface phenomena.
