matlab调用REFPROP8时候出现错误是因为接口文件没有更新,这个是更新版本的,适应于REFPROP8与matlab调用。

% refpropm Thermophysical properties of pure substances and mixtures.
% Calling sequence for pure substances:
% result=refpropm(prop_req spec1 value1 spec2 value2 substance1)
% and for mixtures
% result=refpropm(prop_req spec1 value1 spec2 value2 substance1 substance2 ...x)
% where
% prop_req is a character string showing what properties that are requested
% Each property is represented by one character:
% P Pressure [kPa]
% T Temperature [K]
% D Density [kg/m3]
% H Enthalpy [J/kg]
% S Entropy [J/(kg/K)]
% U Internal energy [J/kg]
% C Cp [J/(kg K)]
% O Cv [J/(kg K)]
% K Ratio of specific heats (Cp/Cv) [-]
% A Speed of sound [m/s]
% X liquid phase and gas phase composition (mass fractions)
% V Dynamic viscosity [Pa*s]
% L Thermal conductivity [W/(m K)]
% Q Quality (vapor fraction) (kg/kg)
% I Surface tension [N/m]
%
% spec1 is a character giving what we want to specify (T P H or D)
% value1 is the corresponding value
% spec2 is a character giving the second specification (P D H S U or Q)
% value2 is the value of the second specification
%
% substance1 is a string with the name of the first (maybe only) substance
% substance2... substance N are the name of the other substances in the mixture.
% Up to 20 substances can be handled
% Valid substance names are equal to the file names in the
% C:\Program Files\REFPROP\fluids\‘ directory (with .FLD excluded).
% is a vector with mass fractions of the substances in the mixture.
%
% Examples:
% 1) P=refpropm(‘P‘‘T‘373.15‘Q‘0‘water‘) gives
% the vapor pressure of water at 373.15 K in [kPa]
% 2) [S Cp]=refpropm(‘SC‘‘T‘373.15‘Q‘1‘water‘) gives
% Entropy and Cp of saturated steam at 373.15 K
% 3) viscmix=refpropm(‘V‘‘T‘323.15‘P‘1e5‘water‘‘ammonia‘[0.9 0.1]) gives
% the viscosity of a 10% ammonia in water at 100 kPa and 323.15 K.
% 4) [x y]=refpropm(‘X‘‘P‘5e5‘Q‘0.4‘R134a‘‘R32‘[0.8 0.2]) gives
% temperature as well as gas and liquid compositions for a mixture
% of two refrigerants at a certain pressure and quality.
% Note that two output variables are needed when ‘X‘ is requested.
