This article assumes that the crude oil in the oil tank of the sunken ship is completely solidified, has high viscosity, and loses fluidity before heating. Based on ANSYS software, a three-dimensional numerical model of the sunken oil tank was…
Heat transfer enhancement in different engineering systems is a major challenge nowadays. Phase change materials can be used for this purpose due to moderate phase change temperature, great thermal capacity, and great latent melting energy. The…
The temperature drop of waxy crude oil after a shutdown is the basic premise for restarting relative mechanical calculation. However, computational accuracy has been paid much more attention excessively in the relevant techniques proposed in the…
The deepwater drilling and cementing techniques achieved significant development in recent years. However, the engineering response mechanism of natural gas hydrate sediment (NGHS) during drilling and cementing process is far from clear, which…
The thermal dissociation process of natural gas hydrate is a Stefan phase change problem with moving boundaries. Based on the conservation integral heat conduction model of the single-phase continuous hydrate control body, the paper establishes the…
The thermal dissociation process that occurs in a natural gas hydrate is a Stefan phase-change problem with moving boundaries. Based on the integral form of a heat conduction model, for a continuous single-phase hydrate control volume, the energy…
By means of additional specific heat capacity and momentum source terms methods, the physical and mathematical models of the heat transfer process of waxy crude oil during its static cooling in the vault tank are established. Through the numerical…
