the performance of water flooding can be investigated by using either detail numerical modeling or simulation, or simply through the analytical buckley-leverett (bl) model. the buckley-leverett analytical technique can be applied to one-dimensional homogeneous systems. in this paper, the impact of heterogeneity on water flooding performance and fractional flow curve is investigated. first, a ba...
one very decisive factor in students’ academic destiny is the result they get at final term examinations. because of its importance, both students and teachers are curiously anxious about them. as normally it is the case, these final term tests are prepared hurriedly in short time by teachers which result in students’ dissatisfaction, complaining on how the test was different from their expecta...
In this article, low velocity impact behavior of fiber metal laminate (FML) composite plates is investigated under three different impact energies (12.7 J, 16.3 J and 24.2 J). Here, three modeling techniques are used. In one of the models the inter-laminar damage is neglected (model without delamination) and in other two models this damage is simulated using cohesive element and cohesive surfac...
abstract nowadays, industries cannot play a crucial role in national and international competitions. the tourism industry is no exception. tourism industry development as the most important economic sector and income generation is one of the key challenges of economic development in the world. therefore, countries were successful that take advantage of the capabilities of tourism sector using ...
this study investigated the potential role of age in inductive and deductive grammar learning among iranian foreign language learners. the experimental population consisted of our randomly selected samples including two groups of children (with age of exposure to english within 8-13), and two groups of adults (with age of exposure to english within 11-13). thus, the comparison was between ch...
study of coupled hydromechanical instabilities, where the notion mechanical instabilities is enriched 13 by complementary (and not necessarily independent) hydraulic with a key role 14 played interfaces and phenomena.Geomaterials are intrinsically multi-phase, porous network being typically saturated mixture Hydromechanical Instabilities in Geomaterials et al. (2009, 2013), to explain formation...
Abstract The sheet metals are prone to large plastic deformation during forming processes. study purpose is investigate 1050A aluminum sheets thermomechanical behavior with ductile damage. A modified Swift model coupled isotropic damage and thermal effects was used. parameters introduced using coefficients Erichsen index. An inverse identification procedure applied non-homogeneous test results....
Machining of Nomex® honeycomb materials is the biggest challenge in industry because complex forms and geometry structure. The latter characterized by a low density with orthotropic mechanical behavior. thin walls composite structure make shaping this material very difficult. Studying interactions between cutting tool material, forces, chip formation allow to understand machining process honeyc...
