Description
Description
One of the disadvantages of frozen gasoline fuel is that the temperature drops during cold seasons or in cold places. When the gasoline temperature drops, sediments and adhesives are removed first. Then heavy hydrocarbon molecules begin to freeze and mummify as temperatures continue to decrease. To prevent the freezing of gasoline, it is necessary to raise the gasoline temperature in the fuel storage tanks. One way to increase the gasoline temperature in the fuel tank is to use pipes carrying the hot fluid flow. The use of helical tubes in situations where space constraints are due to greater heat transfer in a given space is particularly interesting. We designed the 3-D geometry of the model using Design Modeler software. The model consists of two main parts: a fuel tank and a spiral inner tube for hot water flow. We have used ANSYS Meshing software and unstructured mesh for the present model. The total number of cells is equal to 511,821.
Methodology
The present issue concerns the simulation of a gasoline fuel tank carrying a single-way reciprocating spiral tube passing through the tank. This inner tube carries a flow of water at a temperature higher than the temperature of the gasoline to increase the fuel temperature by creating heat transfer between the diesel and the water, thus preventing freezing inside the tank. Therefore, the present model uses a solidification and melting module for the simulation of the phase change material (PCM). The simulation is transient.
Conclusion
The maximum melting occurs near the helical pipes. So the liquid mass fraction will be increased as the heating process continues. This study is carried out in a limited time, and the results are obtained at the end of the simulation.

I found the concept of using helical tubes to prevent gasoline freezing fascinating. Do you provide the specific parameters for the water flowing through the pipes, such as the temperature and flow rate? This could be very useful for someone looking to replicate or understand the specifics of the process.
MR CFD Support –
Yes, the specific parameters of the water flow, like temperature and flow rate through the helical pipes, are included in the tutorial materials. It ensures a comprehensive understanding of how the simulation replicates the heat transfer necessary to prevent the gasoline from freezing.

Mortimer Walsh –
This tutorial sounds very comprehensive. The way the heat transfer between diesel and water is modeled using helical tubes appears very technically innovative. Could you please share more detail on the specific heat transfer mechanisms that were considered in this simulation?
MR CFD Support –
In this CFD simulation, both conduction and convection heat transfer mechanisms are considered. Conduction accounts for the heat transfer within the solid regions of fuel that are experiencing phase change, while forced convection is at play within the helical pipes where the hot water is flowing. The influence of the warm water on the diesel temperature initiates the melting of the solid fuel, which is modeled using the solidification and melting module in ANSYS Fluent software.
