In this study, generalized equations for predicting temperature-dependent
viscosities of jojoba oil/biodiesel (JO-BD) and jojoba oil/diesel blends are
given and a Buddenbrerg–Wilke mixing equation for predicting the viscosities
of the blends is used. For JO-BD blends, the maximum overall absolute average
deviation obtained using the proposed models is 1.85% and it is comparable
with that obtained using Tat and Van Gerpen (1.96%) model and at the same
time lower than those obtained using Walther model (4.61%) and Wang–
Briggs model (4.68%). The results obtained using Buddenbrerg–Wilke mixing
equation are in agreement with those obtained using Arrhenius and Cragoe
mixing models.
