The article deals with the models of analysis of a target product’s load flow in the indignant condition of a production corporation against loss of information definiteness of boundary conditions. The classification of the boundary conditions for the stationary conditions of the studied fragment of system is given
The processes of momentum transfer in laminar and turbulent boundary layers are considered. We have obtained the proprietary models for calculation of shear stresses, turbulent viscosity, friction factors, boundary layer thickness and momentum transfer coefficients in boundary layers under different conditions of motion of media. The examples of the calculation of the above characteristics and their agreement with known experimental data are shown. The obtained equations and the methods of calculation of the boundary layer characteristics can be used for calculations of industrial heat and mass transfer apparatuses of various designs as well as of some other types of equipment
The aim of the article is to study the effect of velocity and acceleration of a drill string on hydrodynamic pressure in a well. We obtain the formulas of pressure versus time. We also established the method for optimizing hydrodynamic pressure in a well at round-trip operations
The article is devoted to the residual on-tolerances in the coating, which are formed with the gradual application of the specific working load and temperature to some of the final values
