the increasing of software’s quality is a significant issue that attracts the attention of many researchers in this field. they are looking for a modeling that meets the users trust and reliance on software. therefore, the demand for high reliability software development has been increased as well. having suitable design, increasing reliability is required. coupling and cohesion are of among di...

This study is concerned with the prediction of particles’ velocity in a dilute turbulent gas-solidboundary layer flow using a fully Eulerian two-fluid model. The closures required for equationsdescribing the particulate phase are derived from the kinetic theory of granular flows. Gas phaseturbulence is modeled by one-equation model and solid phase turbulence by MLH theory. Resultsof one-way and...

There is an increasing need for model coupling. However, model coupling is complicated. Scientists develop and improve models to represent physical processes occurring in nature. These models are built in different software programs required to run the model. A software program or application represents part of the system knowledge. This knowledge is however encapsulated in the program and ofte...
