Functions

Basic Functions for ideal gases: cp, h, s, thermal conductivity, viscosity

Package Contents

cp_T

Compute specific heat capacity at constant pressure from temperature and gas data

cp_Tlow

Compute specific heat capacity at constant pressure, low T region

cp_Tlow_der

h_Tlow

Compute specific enthalpy, low T region; reference is decided by the refChoice input, or by the referenceChoice package constant by default

h_Tlow_der

Compute derivative of specific enthalpy, low T region; reference is decided by the refChoice input, or by the referenceChoice package constant by default

s0_T

Compute specific entropy from temperature and gas data

s0_Tlow

Compute specific entropy, low T region

s0_Tlow_der

Compute derivative of specific entropy, low T region

dynamicViscosityLowPressure
