A general framework for weak residual error estimators applying to various types of boundary value problems in connection with finite element and finite volume approximations is developed. Basic ideas commonly shared by various applications in error estimation and adaptive computation are presented and illustrated. Some numerical results are given to show the effectiveness and efficiency of the...
hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...
در این پژوهش ، جریان دو بعدی و متلاطم سیال غیرقابل تراکم داخل کانال در برخورد با صفحه ضخیم با طول نیمه نهایت به شیوه عددی مورد بررسی قرار گرفته است . هدف اصلی این پژوهش تعیین میدان جریان سیال بوده و بررسی مشخصات ناحیه چرخشی واقع در روی صفحه (به ویژه طول این ناحیه) بیش از هر چیز مورد توجه قرار گرفته است . برای تبدیل معادلات دیفرانسیل حاکم (پیوستگی، ممنتوم، انرژی تلاطم k و نرخ تلفات ارژی جنبشی تل...
the effect of the presence of perforations on he stresses of a plate is a problem which is of great interest in structural design and in the mathemattical theory of elasticity. among the many hole patterns that are likely to require consideration is the ring of equally spaced circular holes. the present worke investigates stress & strain analysis of a thin isotropic circular plate containing a ...
We show how a stable and accurate hybrid procedure for fluid flow can be constructed. Two separate solvers, one using high order finite difference methods and another using the node-centered unstructured finite volume method are coupled in a truly stable way. The two flow solvers run independently and receive and send information from each other by using a third coupling code. Exact solutions t...
