Impact of particle shape and hydrophobicity on the formation of oil particle aggregates: A combined experimental/numerical investigation leading to the formation of a predictive model

The interaction of oil with sediments in the environment could form oil particle aggregates (OPA), which are clumps of oil surrounded by particles. The formation of OPA has been shown to reduce the size of oil droplets and to enhance the degradation of oil. The goal of this experimental and numerical investigation is to evaluate the likelihood of OPA formation, based on different particle properties (e.g. shape, affinity to water) and oil properties (e.g. thick, light, sticky oil), leading to a predictive model for oil cleanup response options. The results will be used to develop and test a software program that enables responders to predict the formation of OPA and the subsequent fate of oil.
