Geophysical Theory

A mixture theory for geophysical fluids

A continuum theory is developed for a geophysical fluid consisting of two species. Balance laws are given for the individual components of the mixture, modeled as micropolar viscous fluids. The continua allow independent rotational degrees of freedom, so that the fluids can exhibit couple stresses and a non-symmetric stress tensor. The second law of thermodynamics is used to develop constitutiv...

Theory and Application of Joint Interpretation of Multimethod Geophysical Data

This work is devoted to the theory of joint interpretation of multimethod geophysical data and its application to the solution of real geophysical inverse problems. The targets of such joint interpretation can be geological bodies with an established dependence between various physical properties that cause anomalies in several geophysical fields (geophysical multiresponse). The establishing of...

Weakly Inhomogeneous Turbulence Theory with Applications to Geophysical Flows

In this study, we investigate the problems of inhomogeneous turbulence. The main goal has been to find the connections between analytic turbulence theories, notably the formalism of the direct interaction approximation (DIA), and turbulence phenomenology. To simplify the results from an inhomogeneous DIA model, we have employed a diagonalization procedure and an assumption of weak inhomogeneity...

2. If the current carrying rod is sufficiently large (a few millimeters in our installation), it is only partly evaporated by a discharge, and the factors influencing performance can be quantitatively studied. In particular, the amount of material melted and evaporated, and the temperatures reached by the current-carrying sheath, called the M-M (metal-megagauss) interface, can be investigated.
