The approach has no explicit constraints on the geometry and temperature distributions of the system and can be easily included with classical electrodynamics...

... ), while partially chaotic systems result in l m ∝ Pe γ , where 0 < γ < 1 ( 22 23 ). Actual value of γ depends on the extent of chaos within the system. For example γ ≤ 0.25 was observed for certain partially chaotic flows ( 7 8 ). The aforementioned...
