An analysis presents the impact of thermal radiation on laminar boundary layer established due to motion a von-Kármán surface. The reason for choosing such shape is its appearance in many aeronautical vehicles, especially F-16 fighter jet nose cone. However, transverse curvature effects are also observable other shapes bodies revolution. But considering practical body revolution provides chance quantify transport phenomena happening sophisticated aerospace vehicles. As result, correct...

Theoretical investigation of a turbulent boundary layer formed over uniformly moving sinusoidal-shaped wavy plate is presented. The primary objective this study twofold: first to report the theoretical treatment considered flow and second investigate quantify potential impacts surface non-flatness on boundary-layer characteristics. Boundary-layer characteristics, such as thickness, momentum coefficient skin friction, shape factor, have been formulated into form similarity variables. modeling...

An investigation has been conducted on the convective heat transfer and entropy production attributable to presence of an infinitely long cylinder in a viscous fluid exhibiting oscillatory motion.

No thermal process, even the biological systems, can escape from long arms of second law. All living things preserve entropy since they obtain energy nutrition consume and gain order by producing disorder.

Abstract The phenomena of flow separation on a surface finite length is analogous to boundary layer flows caused by retarded motion continuous surfaces, which ultimately seize at some downstream position and increase drag aerodynamic vehicles. According the literature, stationary will generate that less energetic than one developed over moving surface. This means preferred for sustainability transport in such flow, must eventually meet separation. Therefore, goal this study conduct heat...

SUMMARY In this paper, we consider the unsteady boundary layer flow of an incompressible viscous fluid produced by periodic motion elastic cylinder.
