in this paper, we use parametric form of fuzzy number and we converta fuzzy linear system to two linear system in crisp case. conditions for the existence of a minimal solution to $mtimes n$ fuzzy linear equation systems are derived and a numerical procedure for calculating the minimal solution is designed. numerical examples are presented to illustrate the proposed method.

This paper tries to achieve a solution for problems that concern condensation around a flat plate, circular and elliptical tube in by numerical and analytical methods. Also, it calculates entropy production rates. At first, a problem was solved with mesh dynamic and rational assumptions; next it was compared with the numerical solution that the result had acceptable errors. An additional suppor...

we show how daubechies wavelets are used to solve kuramoto-sivashinsky type equations with periodic boundary condition‎. ‎wavelet bases are used for numerical solution of the kuramoto-sivashinsky type equations by galerkin method‎. ‎the numerical results in comparison with the exact solution prove the efficiency and accuracy of our method‎.

A model of the spectrum wall-pressure fluctuations under a turbulent boundary layer based on an analytical solution Poisson equation is presented. This suited for aeroacoustic prediction CFD-extracted flow information but requires statistical properties boundary-layer turbulence that are not resolved in steady-state simulations and need to be modelled. For this reason, paper uses Lattice-Boltzm...

For the numerical resolution of the compressible Navier-Stokes equations (NS) with Finite Volumes (FV) two main approaches have called the attention of researchers and engineers. First, following the hyperbolic nature of the compressible NS equations, the Godunov-like schemes discretize the numerical fluxes by a characteristic analysis. Second, disregarding the hyperbolicity of the equations, t...

Thionitrosyl Complexes, Nit rosy 1 Chromium Complexes A nitromethane solution of NS+PFe-, obtained in situ from N3S3CI3 and AgPF6 (1:3), reacts with benzene tricarbonyl chromium in acetonitrile solution to give the thionitrosylcontaining salt [Cr(NS)(NC-Me)s](PF6)2 (1)In the presence of Zerf-butyl isocyanide and Zn powder, 1 is reduced to [Cr(NS)(CN-CMe3)s]PF6 (3), while subsequent oxidation of...

‎the problem of two-phase mhd boundary layer flow, heat and mass transfer over a stretching sheet with fluid-particle suspension and thermal radiation has been studied. the effect of mass transfer in dusty fluid over a stretching sheet is considered for the first time. the governing equations are reduced to a set of non-linear ordinary differential equations under suitable similarity transforma...
