Mathematical model and analysis method for flowfield separation and transition

چکیده

Transition and separation are difficult but important problems in the field of fluid mechanics. Hitherto, transition have not been described accurately mathematical terms, leading to design errors prediction machine engineering. The nonlinear uncertainty involved makes it analyze these phenomena using experimental methods. Thus, new ideas methods required for transition. In this article, after an axiomatic treatment mechanics, concept excited state is derived by generating a fluctuation velocity, revealed that special forms state. This allows us clarify conditions Mathematical analysis Navier--Stokes equations leads general theorem suitable flowfields. Finally, derived, corresponding laws established. results presented article provide foundation future research on mechanism turbulence solution engineering problems.

A Mathematical Model and a Solution Method for Hybrid Flow Shop Scheduling

This paper studies the hybrid flow shop scheduling where the optimization criterion is the minimization of total tardiness. First, the problem is formulated as a mixed integer linear programming model. Then, to solve large problem sizes, an artificial immune algorithm hybridized with a simple local search in form of simulated annealing is proposed. Two experiments are carried out to evaluate th...

A Mathematical Optimization Model for Solving Minimum Ordering Problem with Constraint Analysis and some Generalizations

In this paper, a mathematical method is proposed to formulate a generalized ordering problem. This model is formed as a linear optimization model in which some variables are binary. The constraints of the problem have been analyzed with the emphasis on the assessment of their importance in the formulation. On the one hand, these constraints enforce conditions on an arbitrary subgraph and then g...
