Geometrical Shock Dynamics in a Noble-Abel stiffened gas medium

Autor: Rădulescu, Matei Ioan

We derive the shock strength area rule for a Noble-Abel stiffened gas (NASG) equation of a state required in Whitham's geometrical shock dynamics approach to determine shock wave dynamics in dense gases, liquids and solids. An exact formulation requi

Stiffened gas approximation and GRP resolution for fluid flows of real materials

Autor: Wang, Yue, Li, Jiequan

The equation of state (EOS) embodies thermodynamic properties of compressible fluid materials and usually has very complicated forms in real engineering applications, subject to the physical requirements of thermodynamics. The complexity of EOS in fo

Robust and accurate central algorithms for Multi-Component mixture equations with Stiffened gas EOS

Autor: Kolluru, Ramesh, Rao, S V Raghurama, Sekhar, G N

Simple and robust algorithms are developed for compressible Euler equations with the stiffened gas equation of state (EOS), representing gaseous mixtures in thermal equilibrium and without chemical reactions. These algorithms use a fully conservative

Compressible flow in a Noble-Abel Stiffened-Gas fluid

Autor: Radulescu, Matei Ioan

While compressible flow theory has relied on the perfect gas model as its workhorse for the past century, compressible dynamics in dense gases, solids and liquids have relied on many complex equations of state, yielding limited insight on the hydrody
