Numerical simulation on the thermal process of waxy crude oil during its storage under different wall temperatures

This study aims to elucidate the underlying mechanism of association between heat characteristics and influencing factors provide theoretical guidance for increasing safety economics during waxy crude oil storage. Physical mathematical models with numerical approaches represent static cooling are established. Based on simulations, effect wall temperature velocity distribution is mainly confined thermal influence region near wall, it increases process. The gelation most significant highly correlated convection transfer coefficient so both significantly affected by temperature. In addition, based partial correlation grey analysis, quantitatively analysed. results show that average rate very significant. contrast, sidewall its derived behaviour more Furthermore, detailed information parameters characterize obtained.
