The filling and feeding of thin-walled structures in metal castings pose significant difficulties in manufacturing aerospace structural materials. Samples containing 2 mm and 5 mm thin-walled structures were designed to study the kinetics of filling. The microstructural evolution of the solidification of thin-walled structures was studied with synchrotron X-radiation imaging. The formation of d...
Carbon nanotubes hold vast potential for device innovations because their optical and electronic properties can be synthetically tailored at a length scale unattainable by lithographic techniques. However, lithographic patterning of carbon nanotubes with electronic-type control remains one of the major problems for the integration of these nanomaterials for practical device applications. In thi...
Tube systems are widely used in heat transfer and intensive research is being done on positioning tubes a platform. The platform structure constantly exposed to thermal changes under operating conditions the resulting stresses cause damage existing systems. In this study, 8 thin-walled were positioned flat curved platforms that stress behavior effects was investigated. Finite element analysis u...
The aim of this study was to investigate the potential application metal foams in shell-tube recuperators. A356 aluminium foam cast around internal and external surfaces a thin-walled copper tube enhance heat transfer between separated water streams at different temperatures. results demonstrated that drastically increased efficiency due its large volumetric surface area high thermal conductivi...
