Abstract The present study investigates the behaviour of thermal streaks on a heated foil which is cooled with turbulent flow in square duct channel. Real-time infrared thermography used to visualize and measure spacing between streaks. A stainless-steel thickness 25 microns by water. experiments were performed range Reynolds numbers from 5000 20000 Prandtl 3 7. mean temperature, root-mean-squa...

in the present study, the nonlinear model of non-newtonian blood flow in cosine-shape stenosed elastic artery is numerically examined. the model is carried out for axisymmetric, two-dimensional and fully developed blood flow. the vessel wall is assumed to be have time-dependent radius that is important factor for study of blood flow. the cosine-shape stenosis convert to rigid artery by using a ...
