Examples of singular limits in hydrodynamics
WebAbstract. We consider the hydrodynamic limit of a collisionless and non-di usive kinetic equation under strong local alignment regime. The local alignment is rst considered by Karper, Mellet and Trivisa in [24], as a singular limit of an alignment force proposed by Motsch and Tadmor in [32]. As the local alignment strongly dominate, a weak solution WebIn particular, we will review results about the inviscid limit, the compressible-incompressible limit, the study of rotating fluids at high frequency, the hydrodynamic limit of the …

Webfrom singular limits to explanatory failure, novelty or irreducibility, and then to emergence—is mistaken. The van der Pol nonlinear oscillator is used to show that there can be a full explanation of upper-level properties entirely in base-level terms even when singular limits are present. Whether upper-level properties are emergent depends ... WebExamples of Singular Limits in Hydrodynamics - CORE Reader
Weba body and consider the singular limit as the radius vanishes and the body collapses to a curve. We show that, under mild assumptions, the relation between transport velocities, external loads, and the far-field flow remains well defined and remarkably becomes explicit in this limit; theorems establishing the form of this relation in differ-
