This study presents the effects of periodically moving heat source on a circular steel pipe heated partly from its outer surface under stagnant ambient conditions. While the pipe is heated with this heat source applied on a certain section having a thickness of heat flux, the water flows through it to transfer heat. It is assumed that the flow is a fully-developed laminar flow. The heat source moves...
This work presents numerical analyses of transient temperature and thermally-induced stress distributions in a hollow steel sphere heated by a moving uniform heat source applied on a certain zenithal segment (the heated zenithal segment, ΘH) of its outer surface (the processed surface) under stagnant ambient conditions. Along the process, the moving heat source (MHS) moves...
The purpose of this study is to reduce the thermally induced stress in a solid disk heated by moving ring heat flux (radially periodic expanding and contracting) and cooled by means of coolant following this heat flux (the subsequent cooling process). It was assumed that the ring heat flux per unit area at the each ring surface was uniform. The applied heat transfer rate, Q, regularly increases from...
