Research ArticleOpen accessIn the keywordsTransient MHD Mixed Double Diffusive Convection Along a Vertical Plate Embedded in a Non-Darcy Porous Medium with Suction or InjectionKhaled K. JaberProblem statement: Transient non-Darcy mixed double convection from a semi-infinite, isothermal vertical plate embedded in a homogeneous porous medium, in the presence of surface suction or injection had been numerically investigated. Approach: Forchheimer extension was considered in the flow equations. Appropriate transformations were employed to transform the derived partial differential equations governing the problem under consideration on the assumption of … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 10 Dec 2011 · 7,121 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsHydraulic Characteristics and Pore Water Flow Rule in Constant Rate of Strain ConsolidationA. Ahmadi, A. H. Hoorfar, H. Rahimi, A. SoroushProblem statement: At present study Constant Rate of Strain (CRS) consolidation under Non-Darcy condition was investigated. Approach: In this study a governing conditions on pore water flow were investigated using proposed equation and experimental tests. CRS experiments under different rates of strain were conducted on different soil samples. Results: Results of these experiments and there comparison with proposed equation showed … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,206 accessesView PDF Cite

Research NotesOpen accessIn the keywordsTurbulent-Fluid-Based Simulation of Dynamic Liquefaction Using Large Deformation Analysis of Solid PhaseRohollah TaslimianTo accurately simulate the cyclic liquefaction phenomenon, it is necessary to establish a well-defined coupling between the solid particles and the high-velocity percolating pore fluid. For this purpose, the existing literature extensively examines large deformation liquefaction analyses for the solid phase, regardless of the fluid flow nonlinearity. On the other hand, the transient fluid pressure gradient governed by the turbulence … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 2 · 22 Feb 2024 · 6,015 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordNumerical and Analytical Study of Exhaust Gases Flow in Porous Media with Applications to Diesel Particulate FiltersSuleiman Abu-EinProblem statement: The importance of diesel particulate filter has been increased later because of its ability in making emission reduction of the exhaust gasses. Diesel Particulate Filters (DPF) do two important jobs: gas emissions reduction and noise reduction, the pores spread inside the DPF store some gases and soot emissions and on the other side it prevents some sound or … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,161 accessesView PDF Cite
