External Combustion

The general cycle model of a class of external combustion engines is established in which the influence of the multi-irreversibilities mainly resulting from the linear heat-loss model between the high and low heat reservoir, and the irreversible adiabatic processes. Some important parameters such as the power output, efficiency and the temperatures of the working substance are calculated and some important characteristic curves are given. The results obtained in this paper may provide some theoretical guidance for the optimal design of the Carnot, Brayton, Braysson and some new heat engines.

Analytical Relations

The performance of an isothermal endoreversible chemical engine, in which the mass transfer obeys diffusive law, is analysed and optimized in this paper. The analytical relations about power output and efficiency, as well as the optimal relation between the power output and efficiency of the isothermal chemical engine are derived by using finite-time thermodynamics. Moreover, the optimal operating regions are studied. The results obtained herein can provide some new theoretical guidelines for the optimal design and development of a class of chemical engines.

Thick Glass

High speed photography using the Cranz-Schardin camera was performed to study the crack divergence and divergence angle in thermally tempered glass. A tempered 3.5 mm thick glass plate was used as a specimen. It was shown that two types of bifurcation and branching existed as the crack divergence. The divergence angle was smaller than the value calculated from the principle of optimal design and showed an acute angle.
