Numerical 2D simulation and research on internal flow field and external flow field of rocket motor nozzle using FLUENT software. Analyze the flow condition of internal flow field and external flow field, and according to add in the amount of the different gas components, obtain the clear distribution of contour of density flow field, pressure flow field and various material components and so o...

Nontrivial strong dynamics often leads to the appearance of chiral composites. In phenomenological applications, these can either play role Standard Model particles or lift exotics by partnering with them in mass terms. As a consequence, RG flow may change effective number generations, phenomenon we call generation flow. We provide explicit constructions globally consistent string models exhibi...
