Abstract

"The object of this thesis is to determine by analytical methods the temperatures within a homogeneous plate of finite thickness subjected to a constant temperature on one side and a periodically fluctuating temperature on the opposite side. The heat flow in the other two directions is considered negligible in this problem. Periodic changes of temperature are frequent in nature and in engineering. The surface of the earth is heated periodically by the sun in its daily and annual cycle and the periodic temperature changes below the surface and the question to which depth these changes are appreciable were dealt with by some of the best mathematicians of the 19th century. In the industrial field, on the other hand, periodic changes have to be considered in various constructions, for instance, in thermal engines and in the regenerators of blast furnaces" – Introduction, p. 1.
