The optimum arterial perfusion pressure during cardiopulmonary bypass (CPB) remains uncertain. A correlation in some form with the patients' resting pressure almost certainly exists. Temperature and hematocrit affect blood viscosity. The optimum perfusion pressure during aortic surgery will vary after the initiation of CPB resulting cooling, heating, and hematocrit changes. Poiseuille's Law was...

Nanofluid is prepared through the nanoscale particles suspended in a fluid base and Nanotechnology is a new attempt to investigate the thermal sciences. As a result of huge investment in developed countries on nanotechnology, research on thermal properties of nano-fluids is of particular interest.Due to the usage of nanotechnology to reduce energy waste, in this project CeO2 with EG is used to ...

Effects of some thermo-physical parameters on free convective heat and mass transfer over a vertical stretching surface at lowest level of heat energy in the presence of suction is investigated. The viscosity of the fluid is assumed to vary as a linear function of temperature and thermal conductivity is assumed constant. A similarity transformation is applied to reduce the governing equations i...

We report here the first systematic study of the effect of impurities and additives (e.g., water, chloride, and cosolvents) on the physical properties of room-temperature ionic liquids. Remarkably, it was discovered that the viscosity of mixtures was dependent mainly on the mole fraction of added molecular solvents and only to a lesser extent upon their identity, allowing viscosity changes duri...

Despite its fundamental role in the dynamics of compressible fluids, bulk viscosity has received little experimental attention and there remains a paucity of measured data. Acoustic spectroscopy provides a robust and accurate approach to measuring this parameter. Working from the Navier-Stokes model of a compressible fluid one can show that the bulk viscosity makes a significant and measurable ...
