A simplified semi-analytical model of vertical double U-pipe ground heat exchanger (VDUGHE) was established. The validity the established is examined by contrasting figured outcomes with experiment data, emulation results 3D numerical and calculation infinite line-source (ILSM) for different inlet boundary conditions configurations. After 1 hour, model?s relative error less than 0.32% under con...

Rocks and fossils do not come with labels informing us of their age. They must be understood in light of their geologic context, and interpreted within a worldview. Unfortunately, my evolutionary colleagues are often so dominated by uniformitarian brainwashing they can't objectively understand young-Earth evidence. Nevertheless, some of the evidence is clear and open for all to see. One such cl...

The present study aims to describe the characteristics of hydraulic transport manganese nodules in a vertical pipe. solid–liquid two-phase flows were simulated using numerical technique that combines computational fluid dynamics (CFD) method and discrete element (DEM). Manganese with diameters 5.0 mm, 15.0 30.0 mm selected. effects initial solid volume fraction mixture velocity investigated. re...

This paper investigates numerically the hydraulic conveying of solids through a 90$^{\circ}$ elbow that changes flow direction from horizontal to vertical, in very-narrow case where ratio pipe particle diameters is less than 5. We performed resolved CFD-DEM (computational fluid dynamics - discrete element method) computations, which we made use IB (immersed boundary) method open-source code CFD...
