Trajectory and attitude deviations for internal store separation due to unsteady and quasi-steady test method

Numerical and Empirical Investigation of Flow Separation Phenomenon around Semi-buried Pipelines due to Steady Currents

In this paper, in order to understand the flow-pipe interaction more clearly, the variations on flow pattern around semi-buried pipelines due to steady current have physically and numerically been investigated. In physical modeling section, the experiments have been carried out in a flume with 10 meter length, 0.3 meter width and 0.5 meter depth using a P.V.C pipe with 6.35 cm in diameter (for ...

Steady and unsteady nonlinear internal waves incident on an interface

Steady nonlinear internal waves are commonly described by the Dubreil-JacotinLong equation. This equation contains unknown functions of the stream function, representing the density and vorticity fields. Often these are determined by upstream conditions where the flow is assumed to be known. But for the case when the waves are periodic in the horizontal direction, these functions need to be det...

exploring motivation and english test preparation strategies of iranian pre-university candidates during and at the end of test preparation period for konkur examination

the current study aimed at investigating the relationship between motivation and test preparation strategies (tpss) used by iranian pre-university students in their preparation period for the university entrance exam (uee). due to the importance of uee in iran, this study also attempted to show its impact on these two important variables. to this end, 100 pre-university students in an iranian p...

Simulation of Store Separation using Low-cost CFD with Dynamic Meshing

The simulation of the store separation using the automatic coupling of dynamic equations with flow aerodynamics is addressed. The precision and cost (calculation time) were considered as comparators. The method used in the present research decreased the calculation cost while limiting the solution error within a specific and tolerable interval. The methods applied to model the aerodynamic force...
