OS1307 Mathematical analysis of transient thermal stresses of circular plate subjected to plane axisymmetrical partial heating

Abstract

The purpose of this study is to examine spatial distribution of heat flux at a spot of concentrated light emitted from solar simulator on the surface of a heat receiver and thermo-elastic behaviors of the receiver. A mathematical analysis of a transient thermal stress problem of a circular plate subjected to plane axisymmetrical partial heat supply by the concentrated light is developed. Performing numerical calculation based on the analytical solutions, spatial distributions and time-evolutions of temperature change, thermal stresses and thermal deformations of the plate are examined. The effect of spatial distribution of heat flux is considered under a condition that the quantity of heat per hour flowing into the plate is kept at a constant value.
