Mathematical modeling of mass transfer in a three-phase fluidized system

An algorithm and a program for calculating the driving force of the process of mass transfer and the mass fluxes of gas and liquid phases are developed on the basis of the fundamental two-parameter equation of convective diffusion taking into account the amplitude-frequency characteristics of wave packets. The algorithm and the program of engineering calculation of the processes of physical absorption and chemisorption are written.     

Secondary structures in the friction pair steel-polyurethane with metal powder fillers

The paper discusses structural adaptability during friction from the viewpoint of the theory of self-organization. The friction surfaces and the composition of secondary structures formed during rubbing of steel-45 rollers against polyurethane blocks containing metal powder fillers of various compositions are studied. New secondary structures not characteristic of classical thermodynamics are revealed.     

From Analysis of the Structure of Ultrafine Diamond to the Problem of Its Formation Kinetics

The formation kinetics of ultrafine diamond samples produced by detonation synthesis is inferred from infrared and ultraviolet absorption spectra.     

Analysis of the Uncertainty of Calculations of Loss-of-Coolant Accidents for the No. 1 Unit of the Kursk Nuclear Power Plant

A method is developed for performing statistical analysis of the uncertainty of the hermophysical calculations. This method makes it possible to construct with a prescribed reliability the confidence interval for the estimated parameter, determine the factors which have a large effect on the computational result, and estimate how close the variant calculations are to the base (undeviated) calculation. The methodology has been approved, within the framework of a deeper substantiation of the safety of the No. 1 unit of the Kursk nuclear power plant, for analysis of two types of accidents, using the RELAP5/MOD3.2 computer code, with rupture of the group distribution collector.__________Translated from Atomnaya Energiya, Vol. 98, No. 6, pp. 422–428, June 2005.

Experimental determination of the electrophysical parameters of a forest canopy with the use of signals of the GLONASS and GPS Global navigation systems

The results of an experiment on the use of signals from navigation satellites for determination of the effective complex permittivity (ECP) of a forest canopy are discussed. The signals were received by a unique three-antenna interferometer. For a 30-to 40-year-old pine-forest stand, the real and imaginary parts of the ECP are found to be 1.004–1.01 and 0.008–0.016, respectively, depending on a satellite’s azimuth and elevation angles. The relative errors of these measurements were within 10% and 15%, respectively.
