TL;DR: Advances in Heat Transfer as mentioned in this paper provides in-depth review articles over a broader scope than in traditional journals or texts, which serve as a broad review for experts in the field and are also of great interest to non-specialists who need to keep up to date with the results of the latest research.
Abstract: Advances in Heat Transfer fills the information gap between regularly scheduled journals and university-level textbooks by providing in-depth review articles over a broader scope than in traditional journals or texts. The articles, which serve as a broad review for experts in the field are also of great interest to non-specialists who need to keep up-to-date with the results of the latest research. This serial is essential reading for all mechanical, chemical, and industrial engineers working in the field of heat transfer, or in graduate schools or industry. * Compiles the expert opinions of leaders in the industry* Fills the information gap between regularly scheduled journals and university-level textbooks by providing in-depth review articles over a broader scope than in traditional journals or texts* Essential reading for all mechanical, chemical, and industrial engineers working in the field of heat transfer, or in graduate schools or industry

TL;DR: To evaluate the local hemodynamics in flow limiting coronary lesions, computational hemodynamics was applied to a group of patients previously reported by Wilson et al. (1988) and found the pulsatile flow field was principally quasi-steady before flow separation occurred.

TL;DR: In this article, the authors investigated whether or not the addition of dye altered the viscosity of a transparent liquid such as distilled water and found that the effect was negligibly small as long as the dye concentration was less than 2.
Abstract: A scanning capillary-tube viscometer (SCTV) determines the viscosity of an opaque liquid by measuring the changes in liquid level in two riser tubes. The current SCTV utilizes an optical sensor (i.e. charge-coupled device (CCD)) to measure the changes in the liquid level, where the liquid blocks the path of the light to the optical sensor. For a transparent liquid, one can use dye to make the liquid opaque. Hence, the present study investigated whether or not the addition of dye altered the viscosity of a transparent liquid such as distilled water. In this study, six different concentrations (0.5, 1, 2, 3, 4, and 7 vol.%) of dye were used. The present results demonstrated that the dye effect on the viscosity of dye–water solution was negligibly small as long as the dye concentration was less than 2 vol.%.

TL;DR: In this paper, a method and apparatus for determining the viscosity of a non-Newtonian fluid over plural shear rates using a single capillary tube exposed to a continuously decreasing pressure differential and while minimizing the effects of surface tension of that fluid during the determination is presented.
Abstract: A method and apparatus for determining the viscosity of a non-Newtonian fluid over plural shear rates using a single capillary tube exposed to a continuously decreasing pressure differential and while minimizing the effects of surface tension of that fluid during the determination. A particular application of this method and apparatus is also provided for determining the viscosity of the blood of a living being whereby the single capillary tube initially forms a portion of a hand-held unit that obtains a portion of the circulating blood of the living being; the filled capillary tube is then ejected into an analyzer where the blood therein is exposed to the continuously decreasing pressure differential. Data is generated from the movement of the blood through the capillary tube, due to the decreasing pressure differential, and the blood viscosity is determined from that data.
