Figure 10.

Contrasting of measured HPCR pressures $\mathrm{p}$ with the simulated pressures ${\mathrm{p}}_{\mathrm{simulation}}$ based on the Cross-WLF parameter fits RSS (a) and WRSS (b). A better agreement exists between measured and simulated values for the $\mathrm{d}=1 \mathrm{mm}$ capillaries (circular symbols) than the narrower $\mathrm{d}=0.5 \mathrm{mm}$ capillaries (square symbols). Low Cameron numbers $\mathrm{Ca}$ (Equation (12)) suggest non-isothermal conditions. It could explain the overestimation of the pressures in the isothermal simulations.
