Finite-resolution exhaustive traversal of thermodynamic state spaces has divergent thermodynamic length
Satori Tsuzuki
Mapping an entire multidimensional thermodynamic control region is fundamentally different from driving a system between prescribed endpoints. We formulate such mapping as a finite…
Entropy stability analysis of smoothed dissipative particle dynamics
Satori Tsuzuki
This article presents an entropy stability analysis of smoothed dissipative particle dynamics (SDPD) to review the validity of particle discretization of entropy equations. First,…
Band-Limited Equivalence of Convolution Operators and its Application to Filtered Vorticity Dynamics
Satori Tsuzuki
In this study, we established a general theorem regarding the equivalence of convolution operators restricted to a finite spectral band. We demonstrated that two kernels with ident…
Demonstration of the rotational viscosity transfer across scales in Navier-Stokes turbulence
Satori Tsuzuki
Mechanical effects that span multiple physical scales -- such as the influence of vanishing molecular viscosity on large-scale flow structures under specific conditions -- play a c…
Effects of external gravitational field on highly rarefied gases: Analysis based on stochastic soft-sphere collision models
Satori Tsuzuki
This study examines the effects of an external gravitational field on highly rarefied gases in the transitional-flow regime near the free-molecular-flow regime. In our theoretical…
