Although previous studies have proposed a variety of models to characterize diastolic pressure-flow relations, the models' ability to predict capacitance-free pressure-flow relations from dynamic information in individual studies has not been determined. This study tested the ability of a lumped RC model with pressure-dependent parameters to predict diastolic capacitance-free flow during maximu...

Mineral scale deposition in near wellbore regions of injection wells is one of the main challengeable issues during the water injection process, which magnifies the importance of robust models in predicting the amount of mineral scale deposition such as calcium sulfate. One of the main challenges of CaSO4 scale is in carbonated reservoirs, in which sensitive behavior is observed in related to t...

Abstract The effects of hydrostatic pressure on the defective random one dimensional photonic crystals (1DPC) were investigated for two cases polymeric materials. polymers, Polystyrene (PS), and Polymethyl methacrylate (PMMA) act as defect layer. Where structure is modeled with a combination silicon silica. transmission spectra multilayer structures under are analyzed using transfer matrix meth...

A global nonlinear stability analysis is performed for a couple-stress fluid layer heated from below saturating a porous medium with temperature-pressure dependent viscosity for different conducting boundary systems. Here, the global nonlinear stability threshold for convection is exactly the same as the linear instability boundary. This optimal result is important because it shows that lineari...
