Webb14 apr. 2024 · The increased interest in the transition from liquid to solid polymer electrolytes (SPEs) has driven enormous research in the area polymer electrolyte technology. Solid biopolymer electrolytes (SBEs) are a special class of SPEs that are obtained from natural polymers. Recently, SBEs have been generating much attention … Webb22 sep. 2024 · In this paper, unsteady and time-averaged turbulence characteristics in a submerged cavitating jet with a high Reynolds number are studied using large eddy simulation. The simulation is validated by comparing the vapor distribution using CFD and a high-speed photography experiment. The results indicate that the currently used …

WebbJRC shaped charges are engineered to ensure hole size consistency, maximize formation penetration, and increase flow efficiency to optimize your completion. We offer a full … Perforation by shooting with shaped charge is now commonly used in well completions due to its low cost and high efficiency. In the perforating process, a perforator is exploded to form a jet, which can penetrate the casing, the cement and the rock. The maximum velocity of the jet can reach 8000 m/s in … Visa mer The DP36RDX25-2 perforating gun is selected for simulation. The outer diameter of the casing is 154 mm and the inner diameter 132 … Visa mer The Jones–Wilkins–Lee (JWL) equation is used for the calculation of explosion (Yu et al. 1999; Yan et al. 2024), where V is the volume of the charge, E is the initial ratio of internal energy and … Visa mer To avoid mesh distortions and entanglements, arbitrary Lagrangian–Eulerian (ALE) mesh or adaptive re-meshing … Visa mer Gruneisen state equation is used to describe the dynamic responses, where C is the intercept of vs–vp curve (shear and compressive wave speeds) (Meyers 1994).
