Face validation is an informal type of validation, usually applied in the early stages a simulation project or model development process. used to determine reasonableness when advanced methods such as statistical analysis sensitivity are not applicable. In large-scale projects warfare applications, which consist large number and variety models that cannot be evaluated independently contain high...

Topicality. There is an urgent need to select the main energy, geometric and thermophysical parameters of forest fires, as well assess these including unexplored fire tornadoes wave processes caused by fires. Purpose. To develop mathematical models physical large-scale evaluate Methods. Analytical review research problem, theoretical computational, modeling, systematic analysis set effects. Res...

Water injection is an enhanced oil recovery method which is applied for number of reservoirs especially in the offshore fields around the world. Sea-water injection process is usually associated with important concerns affecting the efficiency, safety, and economy of the operation like formation damage, mineral scaling, early breakthrough and corrosion. Incompatibility between injected and ...

residual gas saturation is one of the most important parameter in determining recovery factor of water-drive gas reservoir. visual observation of processes occurring at the pore level in micromodels can give an insight to fluid displacements at the larger scale and also help the interpretation of production performance at reservoir scale. in this study experimental tests in a glass micromodel w...

dam spillways are the structures that lead rightly and safely the outflow downstream, so that the dam integrity can be guaranteed. many accidents with dams have been caused by an inadequate spillway design or insufficient capacity. to accurately respond the hydraulic spillways, designers use physical modeling for designing this kind of structures. the scale effect in the spillway modeling, as a...

the length of equal minimal and maximal blocks has eected on logarithm-scale logarithm against sequential function on variance and bias of de-trended uctuation analysis, by using quasi monte carlo(qmc) simulation and cholesky decompositions, minimal block couple and maximal are founded which are minimum the summation of mean error square in horest power.
