Flow Across a Cylinder with Hemispherical Head

Direct numerical simulation of flow across a compliant cylinder

A direct numerical simulation (DNS) code is constructed for solving flow across a three-dimensional deformable bluff body. In the present study, DNS of flow across rigid and compliant cylinders is performed to evaluate the code and the drag reduction effect with a compliant coating. The Strouhal number of shedding of the Karman vortex is calculated and it agrees well with that reported in the l...

Thermo-mechanical analysis of a coated cylinder head

This paper presents finite element analysis (FEA) of a coated and uncoated cylinder heads of a diesel engine to examine the distribution of temperature and stress. A thermal barrier coating system was applied on the combustion chamber of the cylinder heads, consists of two-layer systems: a ceramic top coat (TC), made of yttria stabilized zirconia (YSZ), ZrO2-8%Y2O3 and also a metallic bond coat...

Flow and heat transfer behaviour across circular cylinder and tube banks with and without splitter plate

This paper describes the passive flow control of fluid in the downstream direction of the circular tube and in tube banks by means of splitter plate. Heat transfer and pressure drop depend on complex flow pattern of fluid in tube banks, whereas pressure drop linked directly with the fluid pumping capacity. A primary focus is to review experimental, analytical and numerical works that had been c...
