A COMPUTER IMPLEMENTED METHOD OF DETERMINING AT LEAST ONE CONFIGURATION PARAMETER OF A NESTED FLUID TRANSPORT PIPE

Resumen de: WO2025181085A1

A computer-implemented method of determining configuration parameters for a nested fluid transport pipe consisting of an inner and outer pipe. The method involves receiving design constraints for the pipe and performing a computational fluid dynamics simulation to determine a swirl number that represents the swirling motion of the fluid stream. The simulation is performed under the condition that the inner pipe is centred with respect to the outer pipe. Based on the determined swirl number, the method calculates at least one configuration parameter for the nested fluid pipe to achieve the desired level of swirl in the fluid.

A ground source thermal energy transfer device

Resumen de: GB2638665A

A ground source thermal energy transfer device comprising: a conduit 1 (such as a wastewater pipe) having an inner surface (defining a conduit for carrying a fluid) and an outer surface; one or more reinforcement ribs 14 project from and extend around the outer surface of the conduit, the one or more ribs form one or more channels 28 at the outer surface; at least one thermal transfer pipe 34 is arranged within at least one of the one or more channels 28 to exchange thermal energy with a medium surrounding the conduit and/or medium carried within the conduit. The one or more channels may have a height and a width and the diameter of the at least one thermal transfer pipe is substantially equal to the width of the one or more channels. As such, the thermal transfer pipe is received and restrained within the channels and therefore protected by the ribs from compression forces when the conduit is buried in use. The thermal energy transfer device is configured for exchanging thermal energy with another medium such as the surrounding earth or the fluid medium within the conduit.

Resumen de: MX2025009333A

The aspects of the invention include a geothermal system obtains heated heat transfer fluid via heat transfer with an underground reservoir of magma, a wellbore extending between a surface and into the underground reservoir of magma, and a partially cased wellbore having a first borehole portion extending from a surface into an underground magma reservoir. A chamber is located within the borehole and extends at least partially into the underground reservoir of magma. An inlet conduit allows flow of heat transfer fluid from the surface and into the chamber. An outlet conduit allows.flow of heated heat transfer fluid from the chamber toward the surface. The system includes steps of providing a molten salt down a wellbore extending from a surface and into an underground reservoir of magma, receiving heated molten salt from the wellbore, and providing the heated molten salt to a heat-driven process.
