in this work dynamic recrystallization behavior of aisi 403 martensitic stainless steel was studied using hot compression tests over temperature range of 900 c -1200 c and strain rate range of 0.001 s-1 - 1 s-1. the obtained flow curves showed that the hot compression behavior of the alloy is controlled by dynamic recrystallization. the flow stress and strain corresponding to the critical, pe...

This study tested the hypothesis that P2Y12 receptor blockade with clopidogrel preserves renal autoregulatory ability during ANG II-induced hypertension. Clopidogrel was administered orally to male Sprague-Dawley rats chronically infused with ANG II. After 14 days of treatment, whole kidney autoregulation of renal blood flow was assessed in vivo in pentobarbital-anesthetized rats using an ultra...

Entropy generation in adiabatic flow of highly concentrated non-Newtonian emulsions in smooth tubes of five different diameters (7.15–26.54 mm) was investigated experimentally. The emulsions were of oil-in-water type with dispersed-phase concentration (φ ) ranging from 59.61–72.21% vol. The emulsions exhibited shear-thinning behavior in that the viscosity decreased with the increase in shear ra...

PURPOSE Abnormalities in blood vessels by virtue of complex blood flow dynamics is being supported by non-Newtonian behavior of blood. Thus it becomes a focus of research to most of the researchers. Additionally, consideration of real life patient specific model of vessel as well as patient specific inlet flow boundary condition implementation was limited in literature. Thus a thorough implemen...

gums are the most important stabilizers that are used in ice cream and other frozen dairy dessert industries. in this study, effect of different levels of guar gum (0, 0.1, 0.2 and 0.3%) and arabic gum (0, 0.1, 0.3 and 0.5%) on rheological behavior of frozen yogurt was investigated. the rheological behavior of samples showed that all samples exhibit shear thinning behavior and power law model f...

High speed wind tunnels are widely used in the study of fluid flow behavior around various objects. The air flow in the starting step of supersonic wind tunnels is transient including strong shock waves caused by the interaction of the tunnel main stream and the boundary layer at walls. To arrive in running step, the tunnel must be designed so as these waves leave immediately the test section. ...
