The morphing aircraft is a promising solution to achieve an optimal flight performance according to various mission scenarios.To apply the morphing technology in hypersonic vehicles, a variable-sweep-wing morphing waverider was proposed in previous studies, and its aerodynamic performance and dynamic model were presented.In this paper, this morphin

The paper analyzes systems of heat and mass transfer, with heat exchangers of Window Replacement flat surfaces, rectangular, with two liquid thermal agents.The liquids are viscous, slow, and the flows are laminar, type Hagen - Poiseuille or Bingham.It is studied, theoretical and applied, a heat exchanger "in 7.07/7NGR plates" used as a cooler (radi

Crystal facet engineering and nonmetal doping are regarded as effective strategies for improving the separation of charge carriers and photocatalytic activity of semiconductor photocatalysts.In this paper, we developed a facial method for fabricating oxygen-deficient Br-doped BiOCl nanosheets with dominating {001} facets through a traditional hydro
