Hydraulic and gas-dynamic models of a steam-water mixture flow in a granular bed

Tairov E.A., Khan P.V. Hydraulic and gas-dynamic models of a steam-water mixture flow in a granular bed // Journal of Physics: Conference Series. Vol.1382. No.1. ID: 012101. 2019. DOI: 10.1088/1742-6596/1382/1/012101 The paper presents a comparative analysis of the hydraulic and gas-dynamic models of a steam-water mixture flow through a granular bed. The analysis is carried out using experimental data obtained at an inlet pressure of 0.6 - 15.5 MPa, flow quality of 0.002 - 0.3, and mass ...

Numerical solutions of dynamic measurement challenges by volterra equations

... particular properties of the equations under study require the consideration of the floating point arithmetic performed by computers. To evaluate the efficiency of methods that take into account the special properties of the equation, we carried out a comparative analysis between the errors stipulated by those methods and the errors of regularized solutions obtained via the projection regularization method. We demonstrate that the joint application of the approaches based on the middle point rule and ...

Digital Earth and Evolution of Cartography

... quality of the Digital Earth - the cutting-edge technologies, social practices or new scientific principle. In addition, relationship between Digital Earth and Cartography remains unclear. We propose to use the situational awareness as a platform for comparative analysis of different geospatial products and recovery of the internal logic of the evolution of the cartographic method. We demonstrate that Digital Earth is characterized by the use of another mathematical apparatus, rather than the classic ...
