Thermodynamics of Viscous Flows on Surfaces
Anna Duyunova, Valentin Lychagin, Sergey Tychkov
In this paper, thermodynamics of a moving medium is considered. Main goal of this paper is to describe thermodynamics state equations and equations of co-existence manifolds of med…
On Dynamics and Thermodynamics of Moving Media
Anna Duyunova, Valentin Lychagin, Sergey Tychkov
In this paper recent results regarding generalized continuum mechanics on oriented Riemannian manifolds are reviewed and summarized. The mass, the momentum and the energy conservat…
Quotient of the Euler system on one class of curves
Anna Duyunova, Valentin Lychagin, Sergey Tychkov
We consider the Euler system describing a one-dimensional inviscid flows in space along curves of a certain class. Using differential invariants for the Euler system, we obtain its…
Quotients of Navier--Stokes equation on space curves
Anna Duyunova, Valentin Lychagin, Sergey Tychkov
A Navier--Stokes system on a curve is discussed. The quotient equation for this system is found. The quotient is used to find some solutions of Navier--Stokes system. Using virial…
Symmetry classification of viscid flows on space curves
Anna Duyunova, Valentin Lychagin, Sergey Tychkov
Symmetries and differential invariants of viscid flows with viscosity depending on temperature on a space curve are given. Their dependence on thermodynamic states of media is stud…
Symmetries and Differential Invariants for Viscid Flows on a Curve
Anna Duyunova, Valentin Lychagin, Sergey Tychkov
In this paper, flows of a viscid fluids on curves are considered. Symmetry algebras and the corresponding fields of differential invariants are found. We study their dependence on…
