Arun, KR and Rao, Raghurama SV and Lukacova, Medvidova M and Phoolan, Prasad (2007) A Genuinely Multi-dimensional Relaxation Scheme for Hyperbolic Conservation Laws. In: 7th ACFD Conference Bangalore, November 26-30, 2007, J. N. Tata Auditorium, IISc Bangalore.
A novel genuinely multi-dimensional relaxation scheme is proposed. Based on a new discrete velocity Boltzmann equation, which is an improvement over previously introduced relaxation systems in terms of isotropic coverage of the multi-dimensional domain by the foot of the characteristic, a ﬁnite volume method is developed in which the ﬂuxes at the cell interfaces are evaluated in a genuinely multi-dimensional way, in contrast to the traditional dimension-by-dimension treatment. This algorithm is tested on some bench-mark test problems for hyperbolic conservation laws.
