Abstract: This article presents a unified theory that considers both particle friction and interstitial fluid effects for simulating gas–particle flow stress. For the first time, we proposed kinetic theory‐based solid stress equations that can simultaneously take… read more here.

Abstract: We have performed high-order compressible Navier–Stokes simulations of a thermoacoustically unstable resonator employing $\text{CO}_{2}$ in transcritical conditions. The parameter space spans the range of base pressures $p_{0}=1.01-1.5\,p_{cr}$ and temperature differences $\unicode[STIX]{x0394}T=T_{hot}-T_{cold}$ up to 200 K,… read more here.

DOI: 10.1190/geo2017-0080.1
Abstract: ABSTRACTMost subsurface formations of value to exploration contain a heterogeneous fluid-filled pore space, where local fluid-pressure effects can significantly change the velocities of passing seismic waves. To better understand the effect of these local pressure… read more here.
