injection molding is the most widely used process for producing plastic parts.in this process, an important issue is to predict and optimize the warpage before manufacturing. in this paper, a simulation with moldflow software is proposed to optimize the injection molding process. the optimization process aims at minimizing the warpage of the critical injection molding part in which process para...

Engineered Water Injection (EWI) has been increasingly tested and applied to enhance fluid displacement in reservoirs. The modification of ionic concentration provides interactions with the pore wall, which facilitates oil mobility. This mechanism carbonates alters natural rock wettability being quite an attractive recovery method. Currently, numerical simulation this injection method remains l...

Control of a fluid velocity profile by injection and suction of non-ionized flow in presence of a uniform steady magnetic field has important technical applications. In this paper, the unsteady incompressible and viscous conducting fluid flow has been investigated in a circular channel. The channel wall has been assumed to be non-conducting and porous. It has been subjected to a uniform steady ...

This paper introduces an effective production optimization and a water injection allocation method for oil reservoirs with water injection. In this method, a two-stage adaptive simulated annealing (ASA) is used. A coarse-grid model is made based on average horizon permeability at the beginning iterations of the optimization to search quickly. In the second stage, the fine-grid model is used to ...

Background: Osteoporosis is a skeletal disorder which could be influenced by diet. Chronic and excessive alcohol consumption results in increasing risk of osteoporosis. Methods: In the present study, we compared three osteoporosis models of rats, which were generated by gastric tube feeding, intraperitoneal injection and fluid forage feeding with ethanol. All of the Sprague-Dawley rats were ran...
