This paper deals with the one-dimensional unsteady fluid flow model of a natural circulation loop. The governing equations are solved according to both Euler and Lagrange approaches on two parallel computational grids. linearization semi-implicit discretization scheme used enhance algorithm’s effectiveness. results simulations were verified by using experimental data obtained an rig that was sc...

abstract in recent years, dust storm in western part of iran, especially fars province, caused various problems for people. the aim of this research is the identification of circulation patterns producing dust storms over fars province. for this purpose, firstly the code number 6 of current weather at 12 gmt belongs to 8 synoptic stations during the statistical period of 1992-2003 has been extr...
