calc_Bkl_eff(rho, l_ii_avg, Cmol2seg, dii_avg, epsilonii_avg, x0ii, zetax)[source]

Return Bii_avg(rho*Cmol2seg,l_ii_avg) in K as defined in eq. 20.

Parameters:

  • rho (numpy.ndarray) – Number density of system [mol/m^3]

  • l_ii_avg (numpy.ndarray) – Average bead (i.e. group or segment) exponent in component (i.e. molecule) i.

  • Cmol2seg (float) – Conversion factor from from molecular number density, \(\rho\), to segment (i.e. group) number density, \(\rho_S\). Shown in eq. 13

  • dii_avg (numpy.ndarray) – Effective hard sphere diameter of the beads (i.e. groups or segments) in component (i.e. molecule) i.

  • epsilonii_avg (numpy.ndarray) – Average bead (i.e. group or segment) potential well depth in component (i.e. molecule) i.

  • x0ii (numpy.ndarray) – Matrix of sigmaii_avg/dii_eff

  • zetax (numpy.ndarray) – Matrix of hypothetical packing fraction based on hard sphere diameter for groups (k,l)

Returns:

Bii_avg – Bii_avg(rho*Cmol2seg,l_ii_avg) in K as defined in eq. 20.

Return type:

numpy.ndarray
