This paper presents 2-D finite volume method for computation of viscous drag based on Reynolds-averaged Navier-Stokes (RANS) equations. Computations are performed on bare submarine hull DREA and six axisymmetric bodies of revolution with a number of length-diameter (L/D) ratios ranging from 4 to 10. Both structured and unstructured grids are used to discretize the domain around the bodies. Diff...

the islamic revolution helped develop a new discourse and semantic system. one of the methods to study or analyze the political phenomena is critical discourse analysis namely, that of laclau and mouffe›s discourse, the most pertinent. this article examines its main question whether the values of the islamic revolution concepts and identity are constructed, spread and articulated according to l...

Abstract Stokes drag on axially symmetric bodies vibrating slowly along the axis of symmetry placed under a uniform transverse flow Newtonian fluid is calculated. The revolution are considered with condition continuously turning tangent. results sphere, spheroid, deformed egg-shaped body, cycloidal Cassini oval, and hypocycloidal body found to be new. numerical values frictional needle shaped f...

After the establishment of written language, the most revolutionary development in human communication was the invention of the printing press in the 15 th century (1). Before then, books were handwritten, rare, and expensive. Medieval monasteries supported the transcription of new manuscripts from existing ones, and errors were common because of spelling, handwriting, and abbreviation idiosync...
