Simulation of Turbulent Flow Using FEM
An analysis of developing and fully developed turbulent flow was carried out when different techniques have been used in a zone close to the solid wall. In this paper, wall element technique based on the finite element method (FEM) has been adopted and compared with other techniques for determination of confined turbulent flow with a one equation model used to depict the turbulent viscosity is ...
متن کاملinvestigation of effective parameters on the rigidity of light composite diaphragms (psscb) by fem
در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...
Study and simulation of the effective factors on soil compaction by tractors wheels using the finite element method
Soil is a nonrenewable source that needs considerable management to prevent physical deteriorationby erosion and compaction. Compacted soil causes low fertility and yield. The purpose of this study isto investigate the effect of viscoelastic properties of soil and to determine important factors oncompaction. Furthermore, stress distribution, prediction of soil compaction and simulation of its e...
متن کاملForming of Multi layer Sheet Metal by Drawing Process: an Analysis and FEM Simulation
In this paper, the drawing process of multi-layer sheet metal through wedge shaped die has been analyzed using stream function and upper bound method. Typically a sandwich sheet contains three layers of metal, where the outer layers are of the same thickness and material and different from those of the inner layer. In this study, a new deformation model has been introduced in which inlet and ou...
متن کاملHigh Performance FEM Simulation
Processor technology is still dramatically advancing and promises further enormous improvements in processing data for the next decade. On the other hand, much lower advances in moving data are expected such that the efficiency of many numerical software tools for Partial Differential Equations (PDEs) is restricted by the cost for memory access. In this article, we briefly discuss concepts for ...
