Numerical Investigation of Influence of Mesh Property in Nearfield Sonic Boom Prediction [PDF]
Xibei Gongye Daxue Xuebao, 2018 To investigate the influence of mesh property in nearfield sonic boom prediction, the over-pressures of several typical configurations are commutated and analyzed with an in-house Reynolds Average Navier-Stokes solver.

Nonlinear algebraic analysis of delta shock wave solutions to Burgers’ equation [PDF]
Pacific Journal of Mathematics, 2003 This paper uses an abstract algebraic analysis to study delta shock wave solutions to Burgers' equation. It uses three fundamental structures in order to define in a very general way a sheaf of differential algebras that contains within it most of the special cases that are encountered in the theory of generalized functions. By making a suitable choice

A Deposition Model: Riemann Problem and Flux-Function Limits of Solutions
Abstract and Applied Analysis, 2018 The Riemann solutions of a deposition model are shown. A singular flux-function limit of the obtained Riemann solutions is considered. As a result, it is shown that the Riemann solutions of the deposition model just converge to the Riemann solutions of ...

Delta shock wave interactions via wave front tracking method
, 2009 In this paper we discuss delta shock interaction problem for a pressureless gas dynamics system with two different ways of approaching the subject. The first one is by using shadow wave solution concept. The result of two delta shock interactions is delta shock with non-constant speed in a general case. The second one is by perturbing the system with a

Advanced Materials Technologies, EarlyView.Direct nanoscratching with a 500 nm diamond lapping film creates groove‐guided liquid‐crystal alignment interfaces on PCB‐compatible Cu‐patterned RF substrates within minutes, eliminating polymer coating and high‐temperature baking. The coating‐free process enables optical/molecular alignment validation and voltage‐programmable 28 GHz reflection‐phase ...

Advanced Science, EarlyView.This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...
