Eulerian derivation of the conservation equation for energy in a non-inertial frame of reference in arbitrary motion [PDF]

open access: yesApplied Mathematics and Computation, 2021
The standard inertial Navier-Stokes equations consisting of the conservation equations for mass, momentum and energy are often used to investigate the motion of a compressible fluid around an object that is in arbitrary motion.

Study of Solid-Fluid Interaction in Body-Fixed Non-Inertial Frame of Reference

open access: yesJournal of Fluid Science and Technology, 2006
Motion of solid object in fluid is studied in moving frame of reference. Navier-Stokes (N-S) equations in a non-inertial frame of reference is coupled with the equations of linear and angular momentums for the solid object. It is shown that the numerical

ETHER AND EQUIVALENCE OF INERTIAL FRAMES OF REFERENCE

open access: yesInternational Journal of Engineering Technologies and Management Research, 2020
The paper discusses the problem of equality of Inertial frames of reference IFR. The hypothesis of a physical ether, whose properties do not depend on the choice of an inertial reference frame, is proposed. Based on the concept of the physical ether, it turns out the features of instantaneous action at a distance.
