Rapid evaluation method of drag reduction effect for nanoparticles adsorption technology
摘要
Abstract
A new rapid evaluation method of drag reduction effect for nanoparticles adsorption technology was presented in order to simplify the existing evaluation procedure and reduce the evaluation cost. The SEM and contact angle test of the core slice adsorbed by nanoparticles were used to make the pre-evaluation in the new rapid evaluation method, which was based on the analysis of the existing evaluation methods and a lot of experimental drag reduction results of nanoparticles adsorption technology. Based on the theory of drag reduction caused by wall slip, the internal mechanism of the rapid evaluation method was studied by using the simplified model of core composed of capillaries with the same diameter and the relation between slip length and contact angle proposed by Tolstoi. The results show that the new method could make an evaluation effectively and quickly, the evaluation cycle could be shortened and the evaluation cost could be reduced in large amounts. The internal mechanism of the rapid evaluation method is that the contact angle is over 120° through the nanoparticles adsorption on the wall of core micro-channel, which produces phorogenesis and drag reduction effect.关键词
