Abstract In this particular study, we have considered the flow of Casson fluid over inclined flat and cylindrical surfaces, and have conducted a numerical analysis taking into account various physical factors such as mixed convection, stagnation point flow, MHD, thermal radiation, viscous dissipation, heat generation, Joule heating effect, variable thermal conductivity and chemical reaction. Flow over flat plate phenomena is observed aerospace industry, and airflow over solar panels, etc. Cylindrical surfaces are commonly used in several applications interacting with fluids, such as bridges, cables, and buildings, so the study of fluid flow over cylindrical surfaces is… More >

Abstract

A method combining computational fluid dynamics (CFD) and an analytical approach is proposed to develop a prediction model for the variable thickness of the spray-induced liquid film along the surface of a cylindrical workpiece. The numerical method relies on an Eulerian-Eulerian technique. Different cylinder diameters and positions and inclinations of the spray gun are considered and useful correlations for the thickness of the liquid film and its distribution are determined using various data fitting algorithms. Finally, the reliability of the proposed method is verified by means of experimental tests where the robot posture is changed. The

Abstract Within the scope of the piecewise homogeneous body model through the use of the three-dimensional geometrically non-linear exact equations of the theory of elasticity, an approach for the investigation of problems with the micromechanics of a periodically curved fiber near the free convex cylindrical surface is proposed and employed. The main difficulties in finding the solution to these problems are caused by the impossibility of employing the summation theorem for cylindrical functions to satisfy the boundary conditions on the cylindrical surface. For this purpose the cosine and sine Fourier series presentation of the sought values More >
