Similarity:

Mathematical modeling provides a particularly important tool for studying the stream runoff formation processes, and its role is enhanced in the case of a sparse, obsolete monitoring network characteristic of most regions of Siberia. When analyzing spatio-temporal regularities of the water and sediment runoff in river systems, serious problems are caused by lack of the basic hydrological model capable of handling real-time data of hydrological measurements.

Banach Center Publications

Similarity:

Using a one-dimensional hierarchical model based on the Cosserat theory approach to fluid dynamics we can reduce the full 3D system of equations for the axisymmetric unsteady motion of a non-Newtonian incompressible second-grade viscous fluid to a system of equations depending on time and on a single spatial variable. From this new system we obtain the steady relationship between average pressure gradient and volume flow rate over a finite section of a straight constricted tube, and...

Numerical simulation of the two-phase flow through the energetical equipment

Nejedlý, Jan, Vaibar, Roman

Similarity:

A mathematical model of homogeneous and heterogeneous condensation in the turbomachinery is presented. The mathematical model consists of conservation laws of mass, momentum, energy and conservation laws for the description of the rise and growth of water droplets with the homogeneous and heterogeneous condensation. The relaxation method is introduced for solving the two-dimensional unsteady flow through the turbine cascades. The method is developed for unstructured grids and is applied...
