Abstract: Abstract: The Lattice Boltzmann Method continues to garner interest in fluids research, particularly with its ability to accurately simulate laminar flows in the incompressible region. This interest can be attributed in part to the ease of implementation the Lattice Boltzmann Method provides; including a lack of complex differential terms and a linear approximation of the collision operator contained in the Boltzmann equation. In this work, the traditional Lattice Boltzmann solver is augmented with support for immersed boundaries, thermal flows, and microchannel flows. Thermal and micro-enabling support is demonstrated and validated through Rayleigh convection in a square channel and thermally coupled Poiseuille flow through a microchannel, respectively.
