Computational Method for Relative Permeability Curves based on the Bernoulli Generalized Porous Media Equations

Tank Structural Fatigue Fracture in Hydrocarbon Transportation

“…The VST defects analysis showed that there is a change in metal properties [13,14,[16][17][18]: strength, impact hardness and ductility, in particular. Thus, changing metal mechanical properties can be referred to as operational defects of tanks, used in hydrocarbon resource transportation.…”

Effect of section shape on frequencies of natural oscillations of tubular springs

“…To improve the characteristics of manometric springs, a number of spring designs with a cross-section and wall thickness varying along the central axis [6][7][8][9][10][11] are proposed, which may have better performance characteristics than springs of constant cross-section. There are tubular springs with a variable crosssection of the tube, both along the perimeter of the cross section, and along the longitudinal axis of the tube.…”

The Research of Tank Sides Geometrical Forms after their Long-Term Usage in the Oil Transportation System

“…at the junctions of the tank sides. In order to avoid errors and biases in the analysis of the results of measurements deviations of the generatrices, the problem of the representation aggregate sample the obtained values was solved, and interrelation of between the measurement point and the value of the deviations at that point which could be obtained in the study of aggregation was established [16,20].…”
