We develop a geometric formulation of fluid dynamics, valid on arbitrary Riemannian manifolds, that regards the momentum-flux and stress tensors as 1-form-valued 2-forms, and their divergence as a covariant exterior derivative. We review the necessary tools of differential geometry and obtain the ...
Presents a study which investigated gravity wave momentum flux which was induced by thermal force, and its approximation for large-scale models. Proposal of a possible method to parameterize the momentum reflux in large-scale models; How momentum reflux is calculated; Why analytical formulation, the...
A new set of laws of motion for turbulent jets propagating in an intergalactic medium characterized by a decreasing density is derived by applying conservation of momentum flux both in the classical and relativistic framework. Two characteristic features of radio-galaxies, such as oscillations and curv...

when multiplied by the square of the free stream velocity, equals the integral of the momentum defect. Alternatively, the total loss of momentum flux is equivalent to the removal of momentum through a distanceθ. It is a theoretical length scale to quantify the effects of fluid viscosity near ...
