For an evenly spaced lattice, use a ruler and a Food Writer (or small dots of icing). While lines are usually piped with a round tip, try using a small star tip or a basketweave tip to create different widths and texture.

2025年1月7日 · Highlights: • Used Lattice Boltzmann Method model complex internal flow in porous flat heat pipes. • Compared three typical wicks with same porosity, powder wick has best heat transfer. • Microgroove wicks excel in nucleate boiling and preventing film boiling. • Prevent film boiling by improving wick design, surface hydrophilicity, or ...

2022年3月31日 · A new tubular lattice structure is designed based on the "pipe-like" microstructure. Different from the parameter optimization method for classical lattice and the design method of super structured lattice, this method reconstructs the classical lattice to avoid complex new geometric structure design.

2024年11月15日 · Complex pipe geometries such as bends and surface liners create complex fluid boundaries, triggering interactions between fluid flow and acoustics. The lattice Boltzmann method (LBM) excels at capturing these interactions near complex boundaries, in contrast to the finite volume method, which can result in errors.

2018年3月15日 · In this paper, we present a first direct numerical simulation (DNS) of a turbulent pipe flow using the mesoscopic lattice Boltzmann method (LBM) on both a D3Q19 lattice grid and a D3Q27 lattice grid.
