A numerical simulation of the effect evaluation heat loss and temperature distribution along wellbore is performed, for two models, first an open hole (without perforation) other a perforated vertical wellbore. In this study, Computational Fluid Dynamics (CFD) software code ANSYS FLUENT 15.0 has been used, simulate model 3-D turbulent flow with stander k-ϵ model. The results show that, increasi...

A new correlation to estimate the solubility of carbon dioxide in water for the temperature interval of geothermal interest (from 25°C to 350°C) is proposed. This equation was derived from a comprehensive statistical analysis applied to an updated thermodynamical database containing experimental solubility data reported in the literature. In addition, it is also presented a useful equation to q...

introduction: assessing quality of life for patients with shoulder instability may be essential because of the negative impacts of the disease on patient’s life. the aim of the present study, therefore,  was  to  assess  the  internal  validity  and  consistency,  test-retest  reliability,  and convergent validity of the persian version of the oxford shoulder instability score (osis). material ...
