Incompressibility of the Leray-α model for wall-bounded flows

the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

A new eddy-based model for wall-bounded turbulent flows

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

On the Cauchy problem for a Leray-α-MHD model

In this paper, the Cauchy problem for a Leray-α-MHD model is considered for n = 2, 3. When n = 2, global existence for the strong solution is proved even for the cases with partial viscous term. For the 3-D case, various regularity criteria for the strong solution are established.

On a Stochastic Leray-α Model of Euler Equations

We deal with the 3D inviscid Leray-α model. The well posedness for this problem is not known; by adding a random perturbation we prove that there exists a unique (in law) global solution. The random forcing term formally preserves conservation of energy. The result holds for initial velocity of finite energy and the solution has finite energy a.s.. These results are easily extended to the 2D ca...
