Since Priestley utilized the radiant energy of the sun with his burning glass in his famous experiment of 1774, the method has fallen into disuse and the chemist has accepted the water-bath, the hot-air oven, and the furnace as the standard tools for evaporation, drying, and combustion. The boiling water-bath is used for evaporating solutions or drying solids which decompose at temperatures sli...

Thermal radiant heating through distinct heat sources is of interest for the thermal loading of thin objects as it is used in residential applications, furnaces, and insulator designs. In this paper, an optimal design for a thermal radiant system by discrete suspended heat sources is analyzed in a side open cavity used for heating the top plate, while the bottom plate is kept at a constant temp...

This article presents an optimization methodology for finding the heater settings that provide spatially uniform transient heating in manufacturing processes involving radiant heating. Equations governing the transient temperature and temperature sensitivity distributions over the product are first derived using an infinitesimal-area technique and then solved numerically to calculate the object...
