报告摘要:
The Research Center for Aircraft Core Technology (ACTRC) was founded in 2017 with the aim to attack directly the crux of unsolved problems in safety-related core systems of aircraft. The ACTRC envisions, in particular, the development of the critical linchpin technology like aircraft in-flight icing and certification upon which the aircraft industry will hinge.
A unified framework for rarefied and microscale (monatomic and polyatomic) gases and viscoelastic fluids is also discussed in this talk. The conventional description of gases is based on the first-order Navier-Stokes-Fourier constitutive laws. In order to overcome limitations of the linear laws, the second-order algebraic nonlinear coupled constitutive laws derived from the Boltzmann kinetic equation via the balanced closure are introduced and then validated by the atomic-level molecular dynamics simulation.
Lastly, the new 2nd-order laws in conjunction with a discontinuous Galerkin method are applied to several challenging problems; shock structure, nanoscale Poiseuille flow, shock-vortex interaction, rarefied hypersonic flow, and rocket plume-lunar surface interaction and regolith particle dispersal in rarefied dusty gas flow in Lunar landing.
