Research ArticleOpen accessIn the keywordsA New Method for Constructing the Coefficients of Pressure Correction Equation for Colocated Unstructured GridsR. Rafee, H. RahimzadehOne of the important equations in numerical solution of Navier Stokes equations is the pressure correction equation. In this article, a new method for constructing the coefficients of this equation for colocated unstructured meshes is proposed. This method is based on momentum interpolation. The method is compared with the approach adopted in literature. The complete discretization of the Navier Stokes … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,137 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsSimple Improvement of Momentum Interpolation Equation for Navier-Stoke Equation Solver on Unstructured GridAdek TasriProblem statement: Pressure and velocity decoupling have been source of problem in solving Navier-Stokes and continuity equation particularly in complex collocated grid. The problem of pressure velocity decoupling is usually reduced by using momentum interpolation to calculate mass flux at face of control volume. Equation of momentum interpolation was derived by assumption that the face of cell is equidistant from … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 7,858 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFinite Element Analysis of the Crack Propagation for Solid MaterialsMiloud Souiyah, A. Muchtar, Abdulnaser Alshoaibi, A. K. AriffinProblem statement: The use of fracture mechanics techniques in the assessment of performance and reliability of structure is on increase and the prediction of crack propagation in structure play important part. The finite element method is widely used for the evaluation of SIF for various types of crack configurations. Source code program of two-dimensional finite element model had been developed, … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,842 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Adaptation of Fishing Instruments by a Farmers' Community in the Thung Kula Area, in North Eastern ThailandWorawan Ubonlert, Songkhun Chantachon, Worapol EngwanichProblem statement: In a historical study of the ancient communities in the area of Thung Kula, it was revealed that there are important resources including rice, fish, salt and iron. Salt is used in making fermented fish (known locally as Pla Daek), a culinary culture which has been prevalent in the ethnic groups of Laos and Khmer. The availability of … …Journal of Social Sciences, Vol. 5, Issue 2 · 30 Jun 2009 · 7,866 accessesView PDF Cite
