Pressure transient analysis for reservoirs with low mobility coefficient
Актуальные проблемы нефти и газаBackground. Low-permeability reservoirs and reservoirs containing high-viscosity oil are increasingly becoming objects of development due to the deterioration of the reserve structure and a number of negative factors.

Advanced Engineering Materials, EarlyView.This study developed a two‐step laser‐based process for sustainable surface treatment of Ti–6Al–4 V components, combining laser polishing and direct laser interference patterning with ns and ps pulses. Key findings include significant roughness reduction, hierarchical patterning with ps pulses, and improved homogeneity. A cost function is developed for

Behavior of dynamic radial thrust acting on a vertical mixed flow pump impeller
Nihon Kikai Gakkai ronbunshu, 2016 Dynamic fluid forces acting on an impeller of a diffuser type mixed flow pump have been studied. The behavior of the thrust generated by the vortex occurrence in a pump intake sump was investigated.

Method of calculating blade-to-blade plane flow in centrifugal pump [PDF]
, 1970 Steam filament solution determines velocity distribution due to potential flow in the blade-to-blade plane of the radial impeller. This is used to determine the mass-averaged relative fluid angle, which is in turn used in an axisymmetric program to ...

Advanced Engineering Materials, EarlyView.The puncture prevention and energy absorption performance of composite metal foam (CMF) are studied experimentally and numerically for hazardous materials transportation protection. The numerical model implementing air within the CMF (nonhomogeneous model using fluid cavity technique) predicts puncture more accurately compared to the homogeneous CMF ...

APPLICATION OF TDS TECHNIQUE TO MULTIPHASE FLOW EXTENSIÓN DE LA TÉCNICA TDS A FLUJO MULTIFÁSICO
CT&F Ciencia, Tecnología & Futuro, 2008 Although, the radial difussivitity equation has been solved for a single-fluid phase flow, in some cases more than one phase flows from the reservoir to the well; therefore, the single-phase solution has been previously extended to multiphase flow ...

Thermal photon to dilepton ratio in ultra-relativistic heavy ion collisions
, 2009 The ratio of transverse momentum distribution of thermal photons to dilepton has been evaluated. It is observed that this ratio reaches a plateau beyond a certain value of transverse momentum.

Advanced Engineering Materials, EarlyView.Feasibility of improving the mechanical and shape‐memory properties of a CoCrFeMn high‐entropy alloy through carbon addition is investigated. The recovery strain of the carbon‐containing alloy is approximately four to five times higher than that of the carbon‐free alloy.
