LNG physical and chemical parameters.

Physical and chemical parameters	Numerical value	Physical and chemical parameters	Numerical value
Density (kg/m³)	430	Thermal conductivity (W/(m·K))	0.21
Kinematic viscosity (kg/(m·s))	0.0001183	Saturated vapor pressure (Pa)	Piecewise function representation
Latent heat of vaporization (J/kg)	509332	Heat release during pyrolysis (J/kg)	0
Vaporization temperature (K)	90.7	The surface tension of the droplet (N/m)	0.0133
Specific heat capacity (J/kg·K)	2055	Boiling point (K)	111.66

Note. The saturated vapor pressure in the table is a value that changes with temperature, which is defined by a piecewise linear function, as shown in Table 3.
