Novel Method

The present paper reviews the investigation of ambient water structure and focusses in particular on the determination of the radial distribution functions of water from total experimental radiation scattering experiments. A novel method for removing the inelastic scattering from neutron data is introduced, and the effect of Compton scattering on X-ray data is discussed. In addition the extent to which quantum effects can be discerned between heavy and light water is analysed against these more recent data. It is concluded that, with the help of modern data analysis and computer simulation tools to interrogate the scattering data, a considerable degree of consistency can be obtained between recent and past scattering experiments on water. That consistency also gives a realistic estimate of the likely uncertainties in the extracted radial distribution functions, as well as offering a benchmark against which future experiments can be judged.

Optimum Water

The work considers the pre-requisites for the development of a scientific methodology of determination of optimum water content in hard raw mixes used for the production of high-strength concrete. The main idea of the methodology is the capillary structures hypothesis which considers the laws of formation of irregular structures under the conditions of balance of the forces among the particles in three-phase disperse systems. The structure formation under the effects of capillary cohesion in disperse systems has been studied; the capillary cohesion was considered as a factor influencing the formation of the optimum structure of raw mixes for compressed construction composites and determining the strength of the products.

Hydrodynamic Influence

This article concerns the methodological issues of developing principles for increasing the reliability and durability parameters of equipment and auxiliary mechanisms of hydrotechnical structures. An analysis of the conditions ensuring an increase in the accuracy of engineering calculations of the viscosity of disperse systems is carried out. An analytical consideration of the effects of the particle shape on the calculation of the groundwater viscosity using the representations of particles of dispersed media as hydrodynamic dipoles is proposed. An equation for the viscosities of disperse systems is obtained with the determination of the shape factor of solid particles in a liquid. The comparison with the ratios for calculating the viscosity of ideal groundwater consisting of particles of a circular configuration indicates the possibility of reducing errors in calculating the coefficients of permeability of flow rates and pressures of filtration currents in underground horizons under the fluences of hydraulic structures. To improve the reliability of building structural elements operation of spillways without vacuum dams, a method of refined calculation of the dynamic effect of groundwater on the base of spillway dams and dams of the river bed is proposed.
